About this video

Have you seen the 2008 movie Quarantine? this makes the game very similar with the exception that the zombies here wont die.
They keep rising from the dead. This is probably the worst nightmarish situation you never want to be.
Playing this game that way makes it a lot harder and it is almost impossible to win. You only have split seconds to when you turn around just to find a zombie is running at you.
You can never be sure if you are safe or not.
