It is a mixed bag. I do enjoy the game, but a few things then drag it down.
1. No save is annoying
2. The zombies that run in before the screen is fully loaded and kill a survivor before you get a chance to shoot is annoying
3. No headshots
Was fun. But it's so glitchy! I was at Johnstown, and was about to leave, when I suddenly wasn't able to shoot. And the zombies that charge up before your screen is fully on and kills a survivor is ridiculous.
