It's a pretty good game. However, the mines are pretty useless for one thing they are pretty damn expensive. I mean one mine is worth $1000, and once a zombie blows it up it's gone pretty big rip off if you ask me. Either reduce the price to like $100 or take them out, and put something else in to replace it. Something that is actually worth spending 1000 on and is gonna be more effective one the Zombies. This is the only problem I have with the game other than that great job on the game.
