Contagion is a survival horror first-person shooter video game,[1] developed and published for PC by American independent studio Monochrome.

[3] The game was mostly self-funded of its development, but with the support of others via a successful Kickstarter campaign, it was able to be released on Steam as an Early Access title.

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 a location and rescue a number of A.I.-controlled non-player character survivors.

Both Escape and Extraction can be played off-line by a single player, although they are geared towards multi-player gameplay.
