Love the update! The robots are a surprising challenge, and the way the AI reacts now is great. I agree with what another poster said about the robots having a sound when they detect you, sounds great.
The SMG is fun, and the barrel smoke is a nice touch.
But I feel like the pistol is angled down a little bit to my Vive controller, just a little, maybe like a degree or two off.
But other than that great job and I'm excited to see what the next part of this update brings!
