This virtual reality app requires the use of an Oculus Rift and a Rift-mounted Leap Motion Controller (using the VR Developer Mount or unofficial alternative). Before using, enable "Allow Images" through the Leap Motion Control Panel to enable video passthrough. Available for OSX.
Put your hands out in front of you and look with the Oculus to move around. Run into the warriors and they will follow you. You can try to shoot by touching your middle finget to your palm to charge and touch your index finger to your thumb to fire.
This app is under development, more updates soon.
