This game rules!!!
This is a good game and ive killed loads (bout 3,000 kills atm) but there are a still a few things that need doing to make it even more enjoyable.
It can eather be impossibly hard or easy not inbetween like foe example I can now get over 50,000 exp a round or there about i think (well a lot) and the first time i died spectacully.
Also having the base to worry about is kinda annoying with zombies and outher randow things coming at you from all angles you cant really move from your base. All in all I think that this is a good game and it hasd had a lot of time in deloping it! =)
