Heard of it? Zombie survival open world MMO sandbox "game"? I say game because it's a mod for a military simulator (it's currently in alpha stage and glitchy and stuff). I bring DayZ up because it's gotten a lot of attention this past month or so to bring your attention to another game that's been in development for over a year called The War Z. It's basically the same general idea, zombies, survival, open world, MMO. Except it's an actual game. The beta is nearly upon us, and you can sign up on their website http://www.thewarz.com/ , click the pre-order button and sign up for the beta (the pre-order isn't available yet). Also if you go to their Facebook http://facebook.com/warzmmo and like them there's a contest going on to give out beta keys :3 and that's all.

tl;dr
Sign up for The War Z, Like them on Facebook :3
