The weapons that are in this level feel strong and good, the shotgun especially - I don't remember it being so strong before, but it's a lot of fun to use now. As before, the harpoon/chainsaw is a really fun gimmick still.
Level design is good, only complaint that all of the corridords look the same with the same angled ceiling so the map can get confusing at times. Also feels like it's experimenting with colored lights but they look pretty weak at the moment. From what I remember Unity's default lighting is terrible for retro-feeling colored lights so might want to experiment with custom shaders or changing the default lighting calculation.
