Where I can download the first version for VR? In the tfgames.site you said only the first version have VR.
Edit: Someone ask the same in other comment, maybe if you publish the sourcecode someone (like me) can adapt it for VR.
I'm afraid it would require rebuilding the game almost from scratch - the controls, safe UI, and skeletons won't work. That said, I am working on a sequel which will be VR. I expect it out in about six months.
