Freakin' sweet!
This is one of the greatest shooters out on Newgrounds. Freakin' great. You really shouldn't have too much trouble on staying alive if you play smart. My thing was I was expecting the laser cannon to be the greatest thing ever, but it wasn't so if you're reading this don't get suckered in to it. It might be an insta-kill butt having to reload after everyshot will catch ya. Get your bonuses as soon as you can. Especially the two that up your exp. Really good game.
My only major complaint is that it would be soooooo helpful if there was a corpse clean up thing. It could happen automatically or it could be an experience cost. Whichever, getting the corpses and the gore cleaned up between levels would be awesome. Especially when you get to the point where one of the zombies is like a scarlett looking spider thing. The blood makes it really hard to see. Other than that I loved this game.
