This game is definetly a TEN!
(You can save ur game in this game)This game is REALLY AWESOME!Everyone shud try this game if u like zombies,weapons,and defence games,cuz thats what it is.I have a couple of hints for you who die and what not.
1)At the first level,u shud save up ur money for a good starter weapon,like a magnum or different pistol.
2)Dont waste all ur time just shooting the tuff ones,shoot those other zombies,cuz they will still hurt u,so watch it.
3)Try to get the Famas if u want,it will do alot,but also buy other weapons too.
4)NEVER go out and think ur base wont be pwned,cuz they come from everyweres,accpect from behind of course :).
5)My last hint is,to just have fun playing!(If you really hate all the blood thats piling up,w8 till next level,then save ur game,then exit,and play again!
