The first person camera mode has been added in the latest update!
Lets hope the game doesn't explode. Let me know about any bugs.
You can switch to first person in the menu, press F7 or press the right stick. Dolly camera controls like it always has but the first person mode switches run to the right bumper and the camera controls with the right stick. You can also strafe.
The Official Soundtrack Release was planned for today too, but unfortunately Steam needs to approve it before it can go live (which takes a couple days), so be on the lookout soon.
