[quotemsg=20116268,0,2539862]"VR Halo experience" does not mean "VR Halo game". A lot of companies have announced "VR Experiences" for their IPs and then release like a 10 minute "game" called a VR Experience. Don't get your hopes up.[/quotemsg]
Yep, first thought I had was that it could be something along the lines of a shooting gallery, standing in place and holding off waves of oncoming enemies, like any number of other VR shooters. There is a lot they could do with a series like Halo in VR, but that doesn't mean they necessarily will. It's certainly not likely to be something with the scale of a mainline Halo game, at the very least. VR doesn't yet have the install base for them to justify investing tens of millions of dollars into a AAA title for the platform yet. That's why there aren't really any "AAA" titles designed around VR yet.
