Situation Outbreak is an Orange Box mod about the impending zombie apocalypse. Armed with nothing but a 9mm and a pair of brass knuckles, you must do whatever it takes to survive against the thousands of zombies that used to be your friends and neighbors. The cost of failure is nothing less than your free will. There are no heroes. No single person can save the world and there are not enough bullets to go around. The only thing left to do is to kill the damned, hoping that you don’t end up like them.
