Good Game
It's a good game but I agree with some of the previous players, the game needs balance. The third tier assault rifle has high damage and .4 second reload for instance. And @ the last reviewer: It's obvious that he does know defending yourself is easier. The base is there because without it it'd be too easy, if it was just self defense there'd be no challenge in the game.
Greeee-aaaaaattttttt!
Ok so defense mode is tight survial is tighter,now the upgrades and guns total is almost uncountable. The one problem is the bodies of blood become so vast that the oncoming zombies almost have camoflauge making the game challenging, and to say the least very f'n hard! Now there been harder but this small glitch will screw u over soooo bad u wont see it coming in the 13th level, and in defense mode not only do you have to protect yourself but a base in which goes down within three zombie hits the zombies get stronger and faster as the levels go on and the guns u can buy get more awesome.
Good game
It a good game, the graphics are nice but there still room for improvements. It was a bit easy specially after u get Overkill and the laser canon, the you get massive amount of xp and u can buy anything u want. Makes the game kinda pointless. But it still hard when u start of.
very fun game
there are a few things that could be changed like the experiance could be gained faster at the start and that blood goes away because it starts to lag the game
Nice
Very good all around, difficulty was scaled well. Weapon upgrades were nearly perfect, thought after getting the SCAR there was no point in anything else, maybe the minigun, but you cant beat the nearly 200 round clip and .3 reload time of the scar.
Perhaps in the sequel some base defense options like autoturrets, or trenches, or damaging razor wire, something like that.
