perfect game
if ur 1 of the people saying its too hard u shuld break ur arm and never play a game again.The 3rd and 4th day r the only hard days the rest its a fun killing fest specially when u get grenade launcher .This game is much beter than castle defense.I made it to day 35 then stopped playing cus i got it to where i didnt even have to play cus all of my upgrades did all the killing.And too the guy below me buy more bullets b4 u buy a new gun!!!!!!!!!And save ur money!
