This game is the result of Left 4 Dead and Counterstrike having an indie game baby. The graphics are a little dated, but well done and creative. The game is gory and you fight wave after wave of zombies but it is NOT a Left 4 Dead clone. You have to survive the map for a specific time with up to 6 other players all taking on specific job roles wile fighting off successively harder waves of enemies. Note: This is an Indie game. It is not as polished as the big studio releases, but it has alot of heart and the Developers release updates with new monsters and maps with high frequency.
