''Designed support to handle players coming and going during game sessions in multiplayer games.''

Short paragraph giving the description of the pattern while not referring to any other patterns.

=== Examples ===
The multiplayer arcade game [[Gauntlet]] partly supported players leaving and entering the game during a game session. Players whose character had died could start playing again simply by inserting coins and new players could do the same. There was however no graceful way for a player to leave the game when one had a healthy character since that character would keep the others to that area until the abandoned character died (this meant that leaving was worse the more health the character had).

The [[Lego Star Wars Series]] (except the [[Game Boy Advance|GBA]] version) supports a second player to at any point join the game with a character, and then leave whenever by simply choosing this option in the game. Given that the gameplay never requires both players and that players can replay levels infinitely the gameplay does not degrade when a player drops out. 

All game sessions in the [[Left 4 Dead Series]] begin with four human characters but only one of them needs to controlled by human gamers. Those not played by humans are computer-controlled but can be replaced by gamers joining the games session. Likewise, if a gamer leaves the game (or loses network connection) the computer takes control over the character without disruption to the other gamers' gameplay. People can even "pause" the game to take their own short breaks while the other gamers continue with a temporary computer substitute.
