This game is amazing. I think it is kinda smart that zombies take a few bullets to kill, adds a touch of OH MY GOD KILL IT KILL IT KILL IT, BUT DON'T CRASH INTO THAT FUEL TRUCK OHMIGOD.
My only problem is when i do the campaign editor and test it, the game freezes upon my second death, every time. It goes to this dark red screen without any of the menu buttons
But I usually just use level editors to crash my computer with a billion NPCs
