Zombie In My Pocket is a Print & Play game meaning you can download the images for the game for free and run it over your own stock paper to create the game components. Then dust your hands and you're good to go. Of course, if you don't have a professional-grade printer and the materials to print it on then you could just order it for relatively little money here -- it's much better than playing it on normal slips of white paper.
Tom Vasel does a good job breaking down the game and its components in this review filmed from his AstroTurf laden roof top. We're not quite sure why he chose 2nd floor craps table to stage his piece especially since the environment throws the sound off. Still it has us talking so maybe he's on to something.
Anyway, Zombie in My Pocket is 1-8 player twist on a cooperative / competitive board game. The review does a good job of walking through the setup and the rules, so we won't delve too far into that. What we'd like to note is that Zombie in My Pocket was written by a gamer with a degree in psychology, and was designed specifically to cause players to bicker and form friendly disputes in a cooperative survival horror type environment.
Where as games like Pandemic or Battlestar Galactica have you focus on working together, Zombie in my Pocket has you working together as a means to an end. Shrewd players will know when to help out the group to fight some zombies, or quickly run away to let everyone else get gnawed on while they take home the prize.
