A FPS Zombie-survival Sandbox game. One Box Army is probably one of the few Zombie games which actually allows the player to be creative while playing, it is planned that the player should be able to build custom levels with friends or on their own and then play those levels with friends or online. The game should also have support for different modes one where you play with your team or by yourself against all the zombies or where you play in two different teams and maybe see who could kill most zombies or who could find their way out of a maze that someone built, the good thing is that since the player can design their own levels they can make all kinds of challenges.
One Box Army will require Radeon X1900 GT graphics card with a Core 2 Duo E4400 2.0GHz or Athlon 64 X2 Dual Core 4200+ processor to reach the recommended specs, achieving high graphics setting on 1080p. Also your PC needs 2 GB RAM to meet the rec specs and run at 60 frames. Don't try and play One Box Army without 1 GB, which helps get the 30FPS
