Dunno bout WW2, but have a look at Boneworks and The Forest. 
Boneworks is ground-up VR with probably the best physics from any VR game... nothing like glassing some zombie to death, very fun. 
The Forest VR is a pretty nice port of the Forest, just in VR. Its exactly what you would expect from the flatgame, except in VR. If you want to stab savage natives, then its pretty good.
