Playing HL2VR. It's fucking great. I have to play with the laser sight, though, because aiming feels off for some reason. I don't remember vanilla Half Life having bullet spread issues like this. The boss fight against the Hunter-Chopper felt a lot easier, though.

One of my favorite VR games. There's a drum section minigame that's good enough to carry an entire game on its own.
