Holy shit this is great news!
This game is great. You play as a survivor trying to reach a helicopter pad but so is everyone else. The thing that makes this game so great is that you also control zombies and the game is all about screwing the other players.
This really is just stupid amounts of fun. Everyone do yourself a favor and get this game (and I gladly play it with you). If you like board games, get the board game version too.
Also, for a game like this, 200,000 is a lot.
