I was just disappointed that I couldn't shave Michaels head like how it was in the prologue
I think you can, well, kinda, wear the mask that you get with the stealth outfit.Then, go to a lake or river or the beach and dive in the water. Drown in it and then you'll respawn in the hospital with another cut that kinda looks like his prologue one.
I recommend that you use another save as I'm not sure if you have to drown or not. I'm only 99% percent sure that you gotta drown.
