VRaze
This is an amazing native port of the Raze XR engine that plays all the Build engine games like Blood, Shadow Warrior, etc. in VR with 3D Voxel weapons and they work wonderful on my Pico 4 headset. Absolutely recommended to give it a shot if you have any Build Engine game available.
There was some discussion about the sequel to Ion Fury in that thread, but it needs its own thread.
