Noice <- To the max
Alright, the great thing about this game is that I hate zombies with all my soul <3 So with that said, the endless hordes of zombies coming is lovely. It's pretty simple though, and there are some glitches.
After you grab the desert eagle and overkill bonus, you pretty much get everything, you can upgrade your health so high that you can walk away to go get a sandwhich and come back lol
It got laggy when it spawned alot of zombies and if you click the final weapon when you have enough exp, you will get the two previous ones without paying the exp
