Unfortunately, trying to have crossplay between VR and flatscreen on an FPS, in a competitive environment, sounds like a recipe for disaster. Both sides would have some pretty ridiculous advantages in certain ways that would be hard to balance around. 

VR players could do something like easily blind fire around a corner without any real risk or peek corners with their head alone, plus there's potential to reload far faster than preset game animations. On the flip side, flatscreen players would probably have a far easier time snap ADSing for accurate shots or making out fine details and distant views, or aiming things like grenades.

The differences could be kind of fun in something casual or when fighting AI, but in sweaty PVP matches that's asking for a headache.
