When you're an invisible robot, you're invisible to everything but yourself apparently.
I actually played through the entire game without using the Mk II at all. It's one of many play mechanics added to the game that add options to the player, but are not actually necessary to play.
Technically, only a very select few weapons are really necessary to play as well. They just add a lot of extra play options and dimension to the game.
