Contagion is a game played on Game Bang.
Contagion is a multiplayer focused game with 3 different game modes; Hunted, Escape, and Extraction. There is also a beta game mode called Flatline.
Hunted, which supports up to 16 players, is a free-for-all "deathmatch" game mode in which players fight each other, while A.I.-controlled zombies wander the level and serve as an environmental hazard. When a player is killed, they respawn as a zombie and can participate alongside the A.I.-controlled zombies in attacking the surviving players. The goal of the game is to be the last living player.
Escape is a cooperative game mode in which a team of up to 8 players is tasked with progressing through a level, fighting through zombies while completing various mission objectives in a linear order with the ultimate goal of escaping the map.
Extraction is another cooperative game mode in which the goal is to explore an area and rescue a number of A.I.-controlled non-player character survivors.
In both game modes, when a player is killed they respawn as a zombie and are tasked with helping the A.I.-controlled zombies hunt down the remaining human players. Player-controlled zombies are faster and more maneuverable than A.I.-controlled zombie enemies and therefore present a greater threat to human players. Both Escape and Extraction can be played off-line by a single player, although they are geared towards multi-player gameplay.
Flatline is a multiplayer-geared wave based survival mode. The player starts in a singular location, where new parts of the map open every few waves. At the end of a wave, players who died the previous round are resurrected and all players have the option to visit a shop/safehouse and get better weapons/equipment.
