Good game. One flaw.
It was fun. Modestly challenging. Good choice of upgrades. Zombie games never go out of style. Graphics were admirable. The problem was: when you say "Endless Zombie Rampage", you really do mean "ENDLESS Zombie Rampage." By the end of the second day (over two hours into the game), it got pretty repetitive. The guys on the top players' list must have played all day. Eventually there comes a point when there isn't really much reason to keep playing. I'd love to see this game remade with an objective of some kind, besides, you know, not dying forever. My favorite gun was the SCAR.
