Someone is making a custom drivers for existing games that should work it Oculus Rift. Someone asked him about DayZ and this is what he said "ArmA 2 is supported and thus DayZ, I would guess. Although this is one of the cases, where I only worked with the demo so far, so this isn't 100% confirmed. Something might have changed in later patches that breaks the driver. Unlikely, but not impossible. Many things are very game specific in a driver like this." So if we are lucky we could play the game and be inside the world. I am getting my developer edition in few months so i will try it out and let you know. Source : http://www.mtbs3d.com/phpBB/viewtopic.php?f=140&t=16097&start=30
