Running around and killing zombies is  what this game is all about.  There is an interesting story line, and you have to play the single player in order to unlock the co-op mode.

The co-op mode is a lot of fun, If you get stuck with the guy in the wheelchair….maybe not as much.  But at least you can use a pistol to thwart oncoming attacks from the undead.

For 10 bucks retail, I’d say it’s worth it.  Catch it on sale for $7.99 if you hurry through steam.  Good luck and see you in game!
