Imagine if we could do this with GunZ

Experience full virtual reality

We are in the midst of a revolution in virtual reality. The release of affordable head mounted displays and low-cost sensor technologies has brought the decades-old dream of true virtual reality closer than ever, but there’s still one more piece to the puzzle: the Omni.
The Omni takes virtual reality to the next level— allowing anyone to stand up and traverse virtual worlds with the natural use of their own feet. The Omni is the first virtual reality interface for moving freely and naturally in your favorite game. Moving naturally in virtual reality creates an unprecedented sense of immersion that cannot be experienced sitting down. That's why we developed the Omni.
