it's a fun game, but the lag practically kills it, i read some other people saying lag comes at wave 20 something or when they finally get the minigun, but i got the lag like on wave 12. And it's a damn flash game, you don't need the top of the line PC/laptop to run something like this.
there should be a cooldown between waves.
Game was great and well designed I've spent at least an hour playing this game and have probably completed it twice (don't remember how many times I've beat it but i did get all of the achievements). The only lag I experienced was level 25 with the minigun.
The game is good but on wave 20 I used the striker (a shotgun) first time i used it...
and it broke the game
just utterly broke it when i try to move the zombies move with me
and the game is frozen except for the car... i can still fix it
but the bug might be associated with my headphones because it sometimes cuts out and makes steam games give me a black screen.
