Thanks for the great feedback.
The controller is just a rotator so it's possible to flip the camera upside down and sometime Unity picks up mouse inputs during loading times and by the time you're in game the camera can be upside down.
The guards should have a footstep sound effect the player does not. Need to add player stepping sound.
It takes 2 shots to take down a guard and the player has 10. The guards should drop a recharge pack half the time.
I should add an insta for head shots and was going to have a silent stun shot that knocked a guard out for a limited time (and would be half the blaster charge allow 20 shots), but then I would need a body dragging moving system and logic for when the guards find a body.
