Early video games such as [[Pac-Man]] and [[Space Invaders]] have [[Enemies]] which provide challenges to the players even though they have a limited set of behaviors. Later games like the first-person shooter [[Doom series]] and the real-time strategy [[Age of Empires series]] have many types of [[Enemies]] that players need to face.

All the infected in [[Left 4 Dead Series]] are enemies to the players, although some are possible to avoid by not disturbing them. The same applies to [[Assassin's Creed 2]] although this game allows more options for avoiding confrontation, e.g. distracting guards with hired thieves or courtesans as well as bribing heralds to stop being wanted by the authorities.

In fighting games, e.g. the [[Soul Calibur series|Soul Calibur]] or [[Tekken series]], players choose one of the available character to then meet another as an [[Enemies|Enemy]] controlled either by another player or the computer. Similar structures exist in death-match versions in first-person shooters, e.g. the [[Doom series|Doom]] or [[Quake series]], and those game in the genre specifically designed for team play, e.g. [[Castle Wolfenstein: Enemy Territory]] and the [[Battlefield series]].

[[Agents]] in the form of [[Avatars]] or [[Units]] is a typically way of creating [[Enemies]] with diegetic presence in a [[Game Worlds|Game World]]. By this they are natural ways of providing players with ways of interacting with them and understanding how the [[Enemies]] can effect the environment and the players. [[Enemies]] can however be indirectly present through how they create challenges to players, e.g. through [[Cards]] or by activating [[Traps]], which in these cases are also typically accompanied by narrative explanations, e.g. through [[Cut Scenes]]. This indirect approach is especially common when the final [[Enemies]] are [[Boss Monsters]] which the players only get to directly struggle again at the end of the game or [[Levels|Level]].
+
[[Enemies]] may be added to [[Multiplayer Games]] to provide [[Conflicts]] in otherwise [[Cooperation]]-based games or to create [[Complex Gameplay]], but is a necessity in [[Single-Player Games]] that wish to have [[Conflicts]] or [[Combat]]. [[Agents]] in the form of [[Avatars]] or [[Generic Adversaries]] or [[Units]] that have [[Eliminate]] or [[Capture]] goals aimed at the player is a typically way of creating [[Enemies]] with diegetic presence in a [[Game Worlds|Game World]] but [[Game System Player]] provides another option. By this they are natural ways of providing players with ways of interacting with them and understanding how the [[Enemies]] can effect the environment and the players. [[Enemies]] can however be indirectly present through how they create challenges to players, e.g. through [[Cards]] or by activating [[Traps]], which in these cases are also typically accompanied by narrative explanations, e.g. through [[Cutscenes]]. This indirect approach is especially common when the final [[Enemies]] are [[Boss Monsters]] which the players only get to directly struggle again at the end of the game, [[Game Boards]], or [[Levels|Level]]. [[Enemies]] may also only be [[Enemies]] because they are [[Agents]] trying to hinder players' goals toward them, e.g. trying to avoid being the objective in [[Capture]], [[Eliminate]], or [[Herd]] goals.  
  
The cause for enmity between the player and the [[Enemies]] can usually be described through a Goal/[[Preventing Goals|Preventing Goal]] pair. By using high-level goal pairs, the [[Enemies]] can be used as the main driving force for [[Narration Structures]]. Such an overarching goal can then be used to create numerous subgoals within a [[Hierarchy of Goals]]: a [[Collection]] of goals that consist of several duels, [[Gain Information]] goals to gain the identity of the [[Enemies]] or their [[Vulnerabilities]] (or [[Achilles' Heels]]), [[Overcome]] to defeat the henchmen of the [[Enemies|Enemy]], [[Supporting Goals]] to find the [[Tools]], or learn the [[Skills]] for defeating the [[Enemy]], and so on. However, causes compatible with the diegesis need to be found to explain why these [[Enemies]] cannot be encountered early in the game if [[Diegetically Consistency]] is to be maintained. For [[Multiplayer Games]], [[Mutual Enemies]] can be created by making them hostile towards sets of players (and thereby suggesting [[Alliances]] if [[Teams]] are not already present).
+
If [[Enemies]] are permanent or temporary is a basic design choice regarding their use. Permanent [[Enemies]] can be used as the main driving force for [[Narration Structures]] and make the gameplay clearer as their role does not change, and making these [[Enemies]] into [[Predetermined Story Structures]] puts the designers in control of their impact on gameplay. The [[Enemies]] do not have to be present at the start of the game though, they can either be the result of [[Spawning]] or be friendly or neutral entities that at some point change (this being an example of a [[Irreversible Events|Irreversible Event]]), e.g. related to a [[Gain Ownership]] or [[Eliminate]] goal. [[Ever Increasing Difficulty]] can through this be added to a game by guaranteeing that more and more [[Enemies]] or more and more powerful [[Enemies]] oppose players as gameplay progresses.  
  
For game elements to be able to function as [[Enemies]] they need some way of negatively effecting players. Actions that allow [[Combat]] and can remove [[Health]] or [[Lives are the most common, but those giving players [[Penalties]] offer alternatives that do not diegetically imply [[Eliminate]] goals. Since these action reduce players' [[Resources]], [[Enemies]] can often be seen as a form of [[Consumer]]. Giving the [[Enemies]] the possibility of doing the actions players can may be required to provide [[Challenging Gameplay]], e.g. [[Enemies]] without the possibility for [[Movement]] are in themselves typically not a challenge against players that control [[Avatars]] or [[Units]] that can move.
+
The same options regarding when the entities become hostile apply to temporary [[Enemies]]. In addition, these need either a fixed limitation on how long the hostile stance is maintained (which gives rise to an [[Ultra-Powerful Events|Ultra-Powerful Event]] and provides a basis for a [[Time Limits|time-limited]] [[Survive]] goal) or have rules for determining when the change occur. Thus, player may have the options of choosing if they want to try to make [[NPCs]] into [[Helpers]] or [[Companions]], or turning them into [[Enemies]]. This is typically a [[Trade-Offs|Trade-Off]].
  
Another primary design choice when defining [[Enemies]] is how players can [[Overcome]] or [[Evade]] them after they have begun to actively oppose them. There may be many ways to do this, which may change during gameplay, often mirroring the way the [[Enemies]] can effect the players. For more challenging [[Enemies]], and especially [[Boss Monsters]], players may have to complete several subgoals before having the chance to challenge the [[Enemies]] at all. Typical ways of overcoming Enemies are by [[Eliminate|Elimination]] (most often in the form of [[Aim & Shoot]] as in first-person shooters such as the [[Doom series]]), by permanently making [[Interferable Goals]] impossible or by converting through succeeding with [[Gain Ownership]] goals. [[Internal Rivalry]] is a way to use [[Diegetic Consistency]] as a way restrict the ways [[Enemies]] can struggle against each other.

For [[Multiplayer Games]], [[Mutual Enemies]] can be created by making them hostile towards sets of players (and thereby suggesting [[Alliances]] if [[Teams]] are not already present). Sometimes [[Enemies]] can be simply created through providing [[Inhabitants]] with [[Loot]].  
  
The difficulty of [[Enemies]] can be modulated by changing their [[Skills]], equipping them with [[Tools]] (that can become [[Rewards]] if they are [[Transferable Tools]]), giving them [[Privileged Movement]] compared to the players, or simply changing their numbers. All these can be used to provide [[Challenging Gameplay]], and this be further increase (and adding [[Complex Gameplay]] and [[Varied Gameplay]]) by using [[Orthogonal Unit Differentiation]] to give different [[Enemies]] different abilities. One example of this is the inclusion of the Arch-vile in [[Doom 2]] and [[Doom 3]] which can revive other dead [[Enemies]] or summon more respectively, and the priest of [[Age of Empires]] and monks of [[Age of Empires 2]] that can convert enemy [[Units]]. [[Vulnerabilities]] and [[Achilles' Heels]] can instead make the [[Enemies]] easier to [[Overcome]], but may require players to complete [[Gain Information]] goals first.

For [[Enemies]] to actively oppose players they do need some kind of behavior, which can either be controlled by humans or by predetermined structures (i.e. [[Algorithmic Agents]]). Other humans ofter the most unpredictable behavior, so in many cases the most challenging [[Enemies]] are found in [[Multiplayer Games]] but [[Algorithmic Agents]] can also be made very challenging by having [[Privileged Actions]] or more information (i.e. the game has [[Asymmetric Information]]), but this easily conflicts with players' sense of [[Player Balance]] and quite likely also with [[Determinable Chance to Succeed]], especially when this makes the effect of the [[Algorithmic Agents|Algorithmic Agents']] actions into [[Ultra-Powerful Events]]. By definition, [[Game Masters]] can provide unbeatable [[Enemies]] since they can enforce [[Ultra-Powerful Events]] whenever they wish, but this is tempered by their assumed goal of making players have somewhat of a [[Determinable Chance to Succeed]] and an [[Exaggerated Perception of Influence]].
+
Another primary design choice when defining [[Enemies]] is how players can [[Overcome]] or avoid them after they have begun to actively oppose them. There may be many ways to do this, which may change during gameplay, often mirroring the way the [[Enemies]] can effect the players. For example, [[Evade]] goals can allow players to avoid [[Penalties]] the [[Enemies]] can cause but only if these are caused by them succeeding with [[Aim & Shoot]] actions, [[Connection]] goals, or similar (and for this reason this pattern is seen as modulating [[Evade]] rather than instantiating it - it is the threat of [[Penalties]] that is more important). For more challenging [[Enemies]], and especially [[Boss Monsters]], players may have to complete several subgoals before having the chance to challenge the [[Enemies]] at all. Typical ways of overcoming Enemies are by [[Eliminate|Elimination]] (most often in the form of [[Aim & Shoot]] as in first-person shooters such as the [[Doom series]]), by permanently making [[Interferable Goals]] impossible or by converting through succeeding with [[Gain Ownership]] goals. [[Internal Rivalry]] is a way to use [[Diegetic Consistency]] as a way restrict the ways [[Enemies]] can struggle against each other. Related to overcoming [[Enemies]] is the effect of doing so has. Besides fulfilling any eventual goals, the handing out of [[Experience Points]] and [[Loot]] are common design solutions (and may be expected by players in certain genres, e.g. [[:Category:Roleplaying Games|Roleplaying Games]]) and the latter makes [[Enemies]] into potential [[Resource Sources]].  
  
Since setting the difficulty of enemies can be hard to in advanced, especially with games which supports [[Game Mastery]], it may be desired to be able to adjust the difficulty in direct conjunction to the gameplay. [[Difficult Settings]] put this in the hands of the players and can let them choose between [[Casual Gameplay|Casual]] and [[Challenging Gameplay]] if the range of difficulties is large enough. [[Dynamic Difficulty Adjustment]] makes use of algorithms to modify the difficulty of the game during gameplay depending on player performance or number of players. [[Game Masters]] can modulate players' [[

For [[Enemies]] to actively oppose players they do need some kind of behavior, which can either be controlled by humans or by predetermined structures (i.e. [[Algorithmic Agents]]). Other humans (as players or [[Dedicated Game Facilitators]]) ofter the most unpredictable behavior, so in many cases the most challenging [[Enemies]] are found in [[Multiplayer Games]] but [[Algorithmic Agents]] can also be made very challenging by having [[Privileged Abilities]] or more information (i.e. the game has [[Asymmetric Information]]), but this easily conflicts with players' sense of [[Player Balance]] and quite likely also with [[Determinable Chance to Succeed]], especially when this makes the effect of the [[Algorithmic Agents|Algorithmic Agents']] actions into [[Ultra-Powerful Events]]. By definition, [[Dedicated Game Facilitators]] and [[Game Masters]] can provide unbeatable [[Enemies]] since they can enforce [[Ultra-Powerful Events]] whenever they wish, but this is tempered by their assumed goal of making players have somewhat of a [[Determinable Chance to Succeed]] and an [[Exaggerated Perception of Influence]].
Determinable Chance to Succeed]] not only on their actual chance to succeed but also what the players believe, but may also do so after the players have performed actions through [[Fudged Results]].
+
  
Another aspect of [[Enemies]] is if they always behave in the same way or if they have different set of behaviors. Having [[Enemies]] in passive states, as for example some of the infected in the [[Left 4 Dead series]], can provide players the opportunity to have a [[Freedom of Choice]] between [[Combat]] and [[Stealth]] goals. The same goes for [[Enemies]] that patrol areas with [[Guard]] goals, except that this create more [[Complex Gameplay]]. Games providing these different states have the possibility of using [[Alarms]], either as [[Traps]] which players can set off or to give players the [[Preventing Goals]] of hindering the [[Enemies]] to activate the [[Alarms]] when they have detected something. [[Enemies]] that flee when hurt or outnumbered may provide [[Diegetic Consistency]] while at the same time also making it possible to have [[Catch]] or [[Eliminate]] goals before they heal, regroup, or get reinforcements.
+
The difficulty of [[Enemies]] can be modulated by giving them [[Improved Abilities|Improved]] or [[Privileged Abilities]] compared to other [[Enemies]], and this is one way to create [[Boss Monsters]] - the other being to create powerful [[Non-Player Characters]] as [[Enemies]]. Specific ways of improving [[Enemies]] includes changing their [[Stats]] and [[Skills]], equipping them with [[Tools]] (that can become [[Rewards]] if they are [[Transferable Items]]), giving them [[Privileged Movement]] compared to the players, penalizing players with [[No-Ops]], or simply changing how many [[Enemies]] are met. All these can be used to provide [[Challenging Gameplay]], and this be further increase (and adding [[Complex Gameplay]] and [[Varied Gameplay]]) by using [[Orthogonal Differentiation]] to give different [[Enemies]] different abilities. One example of this is the inclusion of the Arch-vile in [[Doom 2]] and [[Doom 3]] which can revive other dead [[Enemies]] or summon more respectively, and the priest of [[Age of Empires]] and monks of [[Age of Empires 2]] that can convert enemy [[Units]]. [[Invulnerabilities]] can easily make [[Enemies]] hard - or too hard - to [[Overcome]] but can be used to force non-violent solutions; For [[Boss Monsters]] the pattern can also be used to force players to first complete a sub goal which makes them vulnerable. [[Vulnerabilities]] and [[Achilles' Heels]] can instead make the [[Enemies]] easier to [[Overcome]] as can [[No-Ops]] applied on them, but these may require players to complete [[Gain Information]] goals first. [[Achilles' Heels]] can also required players' to engage in [[Varied Gameplay]] to take advantage of the enemy weaknesses. [[Clues]] in the form of their appearances, behavior and the [[Traces]] they have left in the game environment can help support this search for information. [[Randomness]] can of course also be applied on the factors which determines the [[Enemies]] difficulty. When this is done, it introduces [[Uncertainty of Information]] and a certain level of [[Varied Gameplay]], and can motivate [[Gain Information]] goals.
  
Related to different set of behaviors, the [[Enemies]] do not have to be opposed to the players initially, instead being neutral or helping but becoming [[Enemies]] after the players have completed some action, e.g. related to a [[Gain Ownership]] or [[Eliminate]] goal. Thus, player may have the options of choosing if [[NPCs]] should be [[Helpers]] or [[Enemies]] which may require [[Tradeoffs]].
+
Since setting the right difficulty of enemies can be hard to in advanced, especially with games which supports [[Gameplay Mastery]], it may be desired to be able to adjust the difficulty in direct conjunction to the gameplay. [[Difficulty Levels]] put this in the hands of the players and can let them choose between [[Casual Gameplay|Casual]] and [[Challenging Gameplay]] if the range of difficulties is large enough. [[Dynamic Difficulty Adjustment]] makes use of algorithms to modify the difficulty of the game during gameplay depending on player performance or number of players. [[Game Masters]] can modulate players' [[Determinable Chance to Succeed]] not only on their actual chance to succeed but also what the players believe, but may also do so after the players have performed actions through [[Fudged Results]].
  
Where [[Enemies]] are met in [[Game Worlds|Game World]] or [[Levels|Level]] also need to be considered . They may block paths to [[Traverse]] goal, which makes their appearance likely or guaranteed, they may be the objectives of [[Reconnaissance]] goals, or may be [[Surprises]] in [[Exploration]] goals. In games requiring [[Maneuvering]] they can provide additional hazards that have to be actively avoided. Some [[Enemies]], typically [[Boss Monsters]], are large enough to be [[Diegetically Outstanding Features]]. Examples of this include the Colossi in [[Shadow of the Colossus]] and some of the [[Boss Monsters]] in the [[God of War series]]. As mentioned above, having several [[Enemies]] appear at the same time is an easy way to make the encounters more difficulty (and may demand [[Attention Swapping]]), but having [[Enemies]] appear separated allows players to decide what [[Enemies]] to challenge first (which can be useful to counter [[Orthogonal Unit Differentiation]]) and provides [[Freedom of Choice]].

Another aspect of [[Enemies]] is if they always behave in the same way or if they have different set of behaviors. Having [[Enemies]] in passive states, as for example some of the infected in the [[Left 4 Dead series]], can provide players the opportunity to have a [[Freedom of Choice]] between [[Combat]] and [[Conceal]] (and thereby [[Stealth]]) goals. The same goes for [[Enemies]] that patrol areas with [[Guard]] goals, except that this create more [[Complex Gameplay]]. Players may not need to choose any of these, but if the [[Enemies]] populate the environment needed to cross to complete [[Traverse]] goals, a choice can be forced from them. Games providing these different states have the possibility of using [[Alarms]], either as [[Traps]] which players can set off or to give players the [[Preventing Goals]] of hindering the [[Enemies]] to activate the [[Alarms]] when they have detected something. [[Enemies]] that flee when hurt or outnumbered may provide [[Diegetic Consistency]] while at the same time also making it possible to have [[Capture]] or [[Eliminate]] goals before they heal, regroup, or get reinforcements. Passive [[Enemies]] also allow players to try and engage in [[Stealing]] [[Transferable Items]] from them.
 +
 
 +
Where [[Enemies]] are met in [[Game Boards|Game Board]], [[Game Worlds|Game World]], or [[Levels|Level]] also need to be considered since placing them in features such as [[Galleries]], [[Sniper Locations]], and [[Strongholds]] can make them much more difficult to [[Overcome]]. Their location may be fixed or based upon [[Randomness]], and can be done either so that the [[Enemies]] are placed before gameplay begin or as [[Game Element Insertion]] during gameplay through [[Spawning]] at [[Spawn Points]]. Their appearance to players may be explain through [[Diegetic Consistency]] or through [[Alien Space Bats]]. [[Waves]] can also be used to introduce many [[Enemies]] are specific points or at specific intervals at [[Levels]] while [[Laning]] can make their appearance predictable but still allow for different choices of tactics and strategies. They can also be used to ensure [[Ever Increasing Difficulty]] due to steadily increasing numbers and difficulties of [[Enemies]].  
 +
 
 +
They may block paths to [[Traverse]] goal (especially easy at [[Choke Points]]), may make areas into [[Inaccessible Areas]], may be the objectives of [[Reconnaissance]] goals as long as there is [[Uncertainty of Information]] regarding their location, or may be [[Surprises]] in [[Game World Exploration]] goals. In games requiring [[Maneuvering]] they can provide additional hazards that have to be actively avoided. Used together with [[Galleries]] or other types of areas that have [[Choke Points]] they can effectively create [[Conditional Passageways]]. These in turn can create (temporary) [[Inaccessible Areas]] until the [[Enemies]] have been dealt with. [[Sniper Locations]] and [[Strongholds]] can also create [[Inaccessible Areas]] but in these cases this is not so much an effect of [[Movement]] being denied as easily being eliminated while moving.

[[Enemies]] give rise to [[Preventing Goals]] for a player, not only in the sense that the player oppose the [[Enemies]] goals but also in the sense that the [[Enemies]] oppose the player's goals. The presence of [[Enemies]] in [[Game Worlds]] causes [[Tension]] and gives players motivation for [[Overcome]] goals, often through [[Combat]]. As such, they naturally cause [[Conflict]] or [[Competition]] as they threaten to make the players lose [[Lives]] or [[Resources]] (working as a form of [[Consumers]]), or otherwise block the players' progress in the game. The presence of [[Enemies]] introduces disturbances, so in this sense they counter [[Stimulated Planning]] by making it more difficult. However, if players have control over when and how they encounter the [[Enemies]] this may encourage [[Stimulated Planning]] before this occurs. A special case of this can be seen in [[Multiplayer Games]], where if players can identify [[Mutual Enemies]] this may form the motivation for creating [[Alliances]].
+
[[Enemies]] are integral to many game themes and therefore necessary for a game's [[Thematic Consistency]]. They may however also need to be modulated according to a game's theme for players to recognize them as [[Enemies]]. While [[Agents]] with goals to [[Capture]], [[Eliminate]], or [[Herd]] game elements belonging to the player make them [[Enemies]], [[Agents]] can also become [[Enemies]] because players have the goals concerning them. In general, [[Enemies]] not controlled by other players create [[PvE]] gameplay.
  
The appearance of [[Enemies]] are nearly always [[Disruption of Focused Attention]] events or [[Surprises]], and can require [[Attention Swapping]] when several different groups of [[Enemies]] exist.

 +
The presence of [[Enemies]] introduces disturbances, so in this sense they modulate or even counter [[Camping]] or [[Stimulated Planning]] by making it more difficult or impossible. However, if players have control over when and how they encounter the [[Enemies]], or if they have [[Vulnerabilities]] or the environment contains [[Environmental Effects]] or [[Traps]], this may encourage and modulate [[Tactical Planning]] and indirectly promote a certain level of [[Stimulated Planning]]. A special case of this can be seen in [[Multiplayer Games]], where if players can identify [[Mutual Enemies]] this may form the motivation for creating [[Alliances]]. Testing and confirming that [[Enemies]] actually have [[Vulnerabilities]] leads to [[Experimenting]] -  this also happens with [[Achilles' Heels]] but then may more take the aspect of [[Puzzle Solving]].

Game elements that are actively hindering players to complete game goals.

Many games have game elements that portray people or monsters that try and hinder players' goals. These Enemies can actively resist players' intentions through actions or they can be an explanation for challenges or obstacles in the Game World.

Examples

Early video games such as Pac-Man and Space Invaders have Enemies which provide challenges to the players even though they have a limited set of behaviors. Later games like the first-person shooter Doom series and the real-time strategy Age of Empires series have many types of Enemies that players need to face.

All the infected in Left 4 Dead series are enemies to the players, although some are possible to avoid by not disturbing them. The same applies to Assassin's Creed 2 although this game allows more options for avoiding confrontation, e.g. distracting guards with hired thieves or courtesans as well as bribing heralds to stop being wanted by the authorities.

In fighting games, e.g. the Soul Calibur or Tekken series, players choose one of the available character to then meet another as an Enemy controlled either by another player or the computer. Similar structures exist in death-match versions in first-person shooters, e.g. the Doom or Quake series, and those game in the genre specifically designed for team play, e.g. Return to Castle Wolfenstein: Enemy Territory and the Battlefield series.

Several games, e.g. Super Mario series, let players know who the main Enemy is but only makes it possible to actively fight him or her at the end. A version of this is to let players know that there is an enemy but only reveal its identity when one can act against it.

Space Alert shows how Enemies can exist in games as more abstract challenges that need to be overcome, in this case card representing threats that players need to work together against to beat.

Using the pattern

Enemies may be added to Multiplayer Games to provide Conflicts in otherwise Cooperation-based games or to create Complex Gameplay, but is a necessity in Single-Player Games that wish to have Conflicts or Combat. Agents in the form of Avatars or Generic Adversaries or Units that have Eliminate or Capture goals aimed at the player is a typically way of creating Enemies with diegetic presence in a Game World but Game System Player provides another option. By this they are natural ways of providing players with ways of interacting with them and understanding how the Enemies can effect the environment and the players. Enemies can however be indirectly present through how they create challenges to players, e.g. through Cards or by activating Traps, which in these cases are also typically accompanied by narrative explanations, e.g. through Cutscenes. This indirect approach is especially common when the final Enemies are Boss Monsters which the players only get to directly struggle again at the end of the game, Game Boards, or Level. Enemies may also only be Enemies because they are Agents trying to hinder players' goals toward them, e.g. trying to avoid being the objective in Capture, Eliminate, or Herd goals.

If Enemies are permanent or temporary is a basic design choice regarding their use. Permanent Enemies can be used as the main driving force for Narration Structures and make the gameplay clearer as their role does not change, and making these Enemies into Predetermined Story Structures puts the designers in control of their impact on gameplay. The Enemies do not have to be present at the start of the game though, they can either be the result of Spawning or be friendly or neutral entities that at some point change (this being an example of a Irreversible Event), e.g. related to a Gain Ownership or Eliminate goal. Ever Increasing Difficulty can through this be added to a game by guaranteeing that more and more Enemies or more and more powerful Enemies oppose players as gameplay progresses.

The same options regarding when the entities become hostile apply to temporary Enemies. In addition, these need either a fixed limitation on how long the hostile stance is maintained (which gives rise to an Ultra-Powerful Event and provides a basis for a time-limited Survive goal) or have rules for determining when the change occur. Thus, player may have the options of choosing if they want to try to make NPCs into Helpers or Companions, or turning them into Enemies. This is typically a Trade-Off.

The cause for enmity between the player and the Enemies can usually be described through a Goal/Preventing Goal pair. Such an overarching goal can then be used to create numerous subgoals within Goal Hierarchies: a Collections of goals that consist of several duels, Gain Information goals to gain the identity of the Enemies or their Vulnerabilities (or Achilles' Heels), Overcome to defeat the henchmen of the Enemy, Supporting Goals to find the Tools, or learn the Skills for defeating the Enemy, and so on. However, causes compatible with the diegesis need to be found to explain why these Enemies cannot be encountered early in the game if Diegetic Consistency is to be maintained. For Multiplayer Games, Mutual Enemies can be created by making them hostile towards sets of players (and thereby suggesting Alliances if Teams are not already present). Sometimes Enemies can be simply created through providing Inhabitants with Loot.

For game elements to be able to function as Enemies they need some way of negatively effecting players. Actions that allow Combat and can remove Health or Lives (and thereby threatening Survive goals) are the most common, but those giving players Penalties offer alternatives that do not diegetically imply Eliminate goals. Since these action reduce players' Resources, Enemies can often be seen as a form of Consumers. Giving the Enemies the possibility of doing the actions players can may be required to provide Challenging Gameplay, e.g. Enemies without the possibility for Movement are in themselves typically not a challenge against players that control Avatars or Units that can move.

Another primary design choice when defining Enemies is how players can Overcome or avoid them after they have begun to actively oppose them. There may be many ways to do this, which may change during gameplay, often mirroring the way the Enemies can effect the players. For example, Evade goals can allow players to avoid Penalties the Enemies can cause but only if these are caused by them succeeding with Aim & Shoot actions, Connection goals, or similar (and for this reason this pattern is seen as modulating Evade rather than instantiating it - it is the threat of Penalties that is more important). For more challenging Enemies, and especially Boss Monsters, players may have to complete several subgoals before having the chance to challenge the Enemies at all. Typical ways of overcoming Enemies are by Elimination (most often in the form of Aim & Shoot as in first-person shooters such as the Doom series), by permanently making Interferable Goals impossible or by converting through succeeding with Gain Ownership goals. Internal Rivalry is a way to use Diegetic Consistency as a way restrict the ways Enemies can struggle against each other. Related to overcoming Enemies is the effect of doing so has. Besides fulfilling any eventual goals, the handing out of Experience Points and Loot are common design solutions (and may be expected by players in certain genres, e.g. Roleplaying Games) and the latter makes Enemies into potential Resource Sources.

For Enemies to actively oppose players they do need some kind of behavior, which can either be controlled by humans or by predetermined structures (i.e. Algorithmic Agents). Other humans (as players or Dedicated Game Facilitators) ofter the most unpredictable behavior, so in many cases the most challenging Enemies are found in Multiplayer Games but Algorithmic Agents can also be made very challenging by having Privileged Abilities or more information (i.e. the game has Asymmetric Information), but this easily conflicts with players' sense of Player Balance and quite likely also with Determinable Chance to Succeed, especially when this makes the effect of the Algorithmic Agents' actions into Ultra-Powerful Events. By definition, Dedicated Game Facilitators and Game Masters can provide unbeatable Enemies since they can enforce Ultra-Powerful Events whenever they wish, but this is tempered by their assumed goal of making players have somewhat of a Determinable Chance to Succeed and an Exaggerated Perception of Influence.

The difficulty of Enemies can be modulated by giving them Improved or Privileged Abilities compared to other Enemies, and this is one way to create Boss Monsters - the other being to create powerful Non-Player Characters as Enemies. Specific ways of improving Enemies includes changing their Stats and Skills, equipping them with Tools (that can become Rewards if they are Transferable Items), giving them Privileged Movement compared to the players, penalizing players with No-Ops, or simply changing how many Enemies are met. All these can be used to provide Challenging Gameplay, and this be further increase (and adding Complex Gameplay and Varied Gameplay) by using Orthogonal Differentiation to give different Enemies different abilities. One example of this is the inclusion of the Arch-vile in Doom 2 and Doom 3 which can revive other dead Enemies or summon more respectively, and the priest of Age of Empires and monks of Age of Empires 2 that can convert enemy Units. Invulnerabilities can easily make Enemies hard - or too hard - to Overcome but can be used to force non-violent solutions; For Boss Monsters the pattern can also be used to force players to first complete a sub goal which makes them vulnerable. Vulnerabilities and Achilles' Heels can instead make the Enemies easier to Overcome as can No-Ops applied on them, but these may require players to complete Gain Information goals first. Achilles' Heels can also required players' to engage in Varied Gameplay to take advantage of the enemy weaknesses. Clues in the form of their appearances, behavior and the Traces they have left in the game environment can help support this search for information. Randomness can of course also be applied on the factors which determines the Enemies difficulty. When this is done, it introduces Uncertainty of Information and a certain level of Varied Gameplay, and can motivate Gain Information goals.

Since setting the right difficulty of enemies can be hard to in advanced, especially with games which supports Gameplay Mastery, it may be desired to be able to adjust the difficulty in direct conjunction to the gameplay. Difficulty Levels put this in the hands of the players and can let them choose between Casual and Challenging Gameplay if the range of difficulties is large enough. Dynamic Difficulty Adjustment makes use of algorithms to modify the difficulty of the game during gameplay depending on player performance or number of players. Game Masters can modulate players' Determinable Chance to Succeed not only on their actual chance to succeed but also what the players believe, but may also do so after the players have performed actions through Fudged Results.

Another aspect of Enemies is if they always behave in the same way or if they have different set of behaviors. Having Enemies in passive states, as for example some of the infected in the Left 4 Dead series, can provide players the opportunity to have a Freedom of Choice between Combat and Conceal (and thereby Stealth) goals. The same goes for Enemies that patrol areas with Guard goals, except that this create more Complex Gameplay. Players may not need to choose any of these, but if the Enemies populate the environment needed to cross to complete Traverse goals, a choice can be forced from them. Games providing these different states have the possibility of using Alarms, either as Traps which players can set off or to give players the Preventing Goals of hindering the Enemies to activate the Alarms when they have detected something. Enemies that flee when hurt or outnumbered may provide Diegetic Consistency while at the same time also making it possible to have Capture or Eliminate goals before they heal, regroup, or get reinforcements. Passive Enemies also allow players to try and engage in Stealing Transferable Items from them.

Where Enemies are met in Game Board, Game World, or Level also need to be considered since placing them in features such as Galleries, Sniper Locations, and Strongholds can make them much more difficult to Overcome. Their location may be fixed or based upon Randomness, and can be done either so that the Enemies are placed before gameplay begin or as Game Element Insertion during gameplay through Spawning at Spawn Points. Their appearance to players may be explain through Diegetic Consistency or through Alien Space Bats. Waves can also be used to introduce many Enemies are specific points or at specific intervals at Levels while Laning can make their appearance predictable but still allow for different choices of tactics and strategies. They can also be used to ensure Ever Increasing Difficulty due to steadily increasing numbers and difficulties of Enemies.

They may block paths to Traverse goal (especially easy at Choke Points), may make areas into Inaccessible Areas, may be the objectives of Reconnaissance goals as long as there is Uncertainty of Information regarding their location, or may be Surprises in Game World Exploration goals. In games requiring Maneuvering they can provide additional hazards that have to be actively avoided. Used together with Galleries or other types of areas that have Choke Points they can effectively create Conditional Passageways. These in turn can create (temporary) Inaccessible Areas until the Enemies have been dealt with. Sniper Locations and Strongholds can also create Inaccessible Areas but in these cases this is not so much an effect of Movement being denied as easily being eliminated while moving.

Some Enemies, typically Boss Monsters, are large enough to be Diegetically Outstanding Features. Examples of this include the Colossi in Shadow of the Colossus and some of the Boss Monsters in the God of War series. As mentioned above, having several Enemies appear at the same time is an easy way to make the encounters more difficulty (and may demand Attention Swapping), but having Enemies appear separated allows players to decide what Enemies to challenge first (which can be useful to counter Orthogonal Differentiation) and provides Freedom of Choice.

Diegetic Aspects

Typically Enemies are clearly differentiated from other game elements through shape and color to help make them into Diegetically Outstanding Features so players become aware of them. However, by presenting the Enemies in ways suitable, players can have Identification with them it can create a form of Social Dilemma as can having to perform certain actions to Overcome the Enemies.

Narrative Aspects

Many games show Enemies to the players through Cutscenes before they can interact as a way of presenting Predetermined Story Structures, and this is especially common with Boss Monsters.

Consequences

Enemies are integral to many game themes and therefore necessary for a game's Thematic Consistency. They may however also need to be modulated according to a game's theme for players to recognize them as Enemies. While Agents with goals to Capture, Eliminate, or Herd game elements belonging to the player make them Enemies, Agents can also become Enemies because players have the goals concerning them. In general, Enemies not controlled by other players create PvE gameplay.

Enemies give rise to Preventing Goals for a player, not only in the sense that the player oppose the Enemies goals but also in the sense that the Enemies oppose the player's goals. The presence of Enemies in Game Worlds causes Tension and gives players motivation for Overcome goals, often through Combat or Capture, but sometimes through succeeding in Herd goals through Maneuvering. As such, they naturally cause Conflicts or Competition as they threaten to make the players lose Lives or Resources (working as a form of Consumers), or otherwise block the players' progress in the game. Enemies with Reconnaissance goals can give rise to both Conceal goals for players and the need for Rhythm-Based Actions.

The presence of Enemies introduces disturbances, so in this sense they modulate or even counter Camping or Stimulated Planning by making it more difficult or impossible. However, if players have control over when and how they encounter the Enemies, or if they have Vulnerabilities or the environment contains Environmental Effects or Traps, this may encourage and modulate Tactical Planning and indirectly promote a certain level of Stimulated Planning. A special case of this can be seen in Multiplayer Games, where if players can identify Mutual Enemies this may form the motivation for creating Alliances. Testing and confirming that Enemies actually have Vulnerabilities leads to Experimenting - this also happens with Achilles' Heels but then may more take the aspect of Puzzle Solving.

The appearance of Enemies are nearly always Disruption of Focused Attention events or Surprises. The presence of them in turn create Attention Demanding Gameplay and can require Attention Swapping when several different groups of Enemies exist.
