This is the famous "Stroggification" of Corp. Matthew Kane, and it's pretty violent. We now move faster, have more health, and can use the wall-mounted Health Units. The downside? The game is done holding our hand and is a lot harder, the levels quite a bit longer.
Rant is you should dress better. And take better care of yourself. It's nice to wear nice clothes.
