PUBG for the Battle Royale genre.
Battlefield Bad Company 2 for FPS, old game, but still an active community.
BF1, I bought it on sale at weekend for £4, excellent game and one of the best looking games I’ve ever played
BF5 is out soon and there’s an open beta next month
Arma3 for a slow tactical FPS, plenty of mods too
Pavlov VR Counter Strike/CoD VRFPS (my go to FPS, there’s 100’s of the community made maps free from steam workshop)
Onward VR for a slow tactical VRFPS
For me nothing beats the sheer adrenaline of playing an FPS game in VR, in a flat game you move out of cover and press R to reload, in VR you physically duck into cover, and then you eject the magazine, reach to your hip grab a fresh magazine and insert it into your weapon and then move out of cover and get back into action, nothing comes close to VR
