It's my favorite zombie survival game, just posting this up for anyone else who is interested. I'm definitely going to be playing this today, lol.
If you haven't tried it out yet, I highly recommend giving the game a try. It is a lot of fun and a great way to waste an hour or two, especially if you're a fan of the whole "zombie survival" theme. The game's a "free zombie survival roguelike sandbox game" which focuses more on the player's ability to survive than running around gunning down zombies.
