Killing zombies was never so fun!
So I bought the game for $5 or $10. I thought to myself, "Whatever, at least I get to kill zombies."
I jumped into a game with 3 other people already blowing zombies the F away... and I was delighted. I was hooked. Playing with other people who know what they are doing, was much more immersive than the single player experience. I was hooked.
Fast paced, and exciting, with enough breaks in the action that you do not feel hounded. Very team oriented. A bad team won't survive long... and a good team will sometimes barely take any damage. The difference is impressive.
I would recommend this game to any of my friends who love FPS, and especially to those who love killing zombies.
A most pleasant surprise from a game I didn't expect much from.
