Contagion Contagion is a cooperative zombie survival first person shooter built on the latest Source Engine. The official sequel to Zombie Panic! Source throws players into an apocalyptic Zombie overridden world left to survive in any way possible. Survivors must conserve ammo, move stealth-fully and aim carefully otherwise be overrun by the zombie hordes, and sometimes other players. Eugene, Marcus, and other Survivors return in the spiritual successor of the popular Half-Life 2 Modification Zombie Panic: Source! Zombie Gaming is currently hosting both East Coast and West Coast Contagion Servers. Reach out to us in the Contagion forum with any questions or requests. We are currently looking for help to grow Contagion into our community.
