Zombday Apocalypse is an AR game for iOS that was developed for my mSC research project. It is a local multiplayer zombie survival shooter game, where the player moves around in any environment and is attacked by zombies that avoid walls and come in through doors, openings etc. It is a multiplayer game and therefore you can play with your friends and shoot down the same zombies. Heck, if you care more about your life and score than your friends you might as well run to get the health and ammo bars that some zombies drop. Finally, don't forget to use the real life environment to your advantage!
