Difference between revisions of "Choke Points"

Revision as of 11:20, 16 July 2011

Areas in game worlds which can be used to block access to other areas.

This pattern is a still a stub.

Examples

Choke Points are used in maps for many multiplayer First-Person Shooters as they concentrate gameplay activity.

For Team Fortress 2, examples include the tunnel in the Gold Rush map and the blue team's initial exit points in the Dustbowl map.

Using the pattern

Choke Points can be create through designing narrow sections in Game Worlds or Levels that solely or together with just a few other Choke Points provide access between other parts of the Game Worlds or Levels. Alternatively, Inaccessible Areas, Obstacles or Environmental Effects can be used and Environmental Effects can make the use of Choke Points a Tradeoff rather than a requirement. Of course, if several Choke Points exist between the same areas - which makes them into Flanking Routes - then players also have a choice whether to use a particular Choke Point or not. The existence of Flanking Routes may however make locations stop functioning as Choke Points if they always offer easier access to other parts of the Game Worlds.

Consequences

Selectable Set of Goals

Can Instantiate

Choke Points are Strategic Locations that affect how Movement can be done in Game Worlds and Levels, primarily by creating Inaccessible Areas. By doing so they are often the targets of Area Control goals regardless of if it is players or their Enemies controlling the Choke Points; this quite naturally leads to to Eliminate goals. The resulting Combat against Enemies is typically easier or harder than "normal" Combat depending on who controls the Choke Points and also likely shift which weapons are most efficient (powerful but short ranged weapons, such as the flamethrower of the Pyro in Team Fortress 2, is most efficient in Choke Points). Besides creating Elminate goals]], Choke Points can create Guard goals and make Stealth goals more difficult.

Repeated Domination

The existence of Choke Points can make areas connected by the Choke Points into Strongholds.

History

New pattern created in this wiki. However, it was first introduced using another template by Hullett and Whitehead^[1], and a more detailed description in this template is available^[2].
