Here's an idea for the tutorial mission Yahtzee.
Your objective is to scare the shit out of this particular official who works at the place you're trying to break into. The level features a lot of theatrics, which you set up yourself as an invisible man, by sneaking into his study before he gets home, which in itself contains a bit of alarm disarming and such. You can set up little, rigged UV lights around the room, complete with a tiny floor button for you to step on to activate them, whilst you're covered in a special UV ink which shows up as invisible as you are in regular light.
Anyway, when he gets home, your target goes to his den and relaxes behind a desk or whatnot, smoking a pipe (a tutorial in of itself about moving through the air slowly so as not to leave any tells in elements such as smoke, steam, etc.) and you creep behind him and start whispering to him. You may have to dodge the occasional backwards swipe, but as you get his creeped-out factor to a high enough level he will start moving around and freaking himself out, shouting and generally being paranoid as fuck.
Once it gets to this point, you sneak to the centre of the room and click on the button, showing yourself in full, creepy UV makeup to fill his pants and ensure he does whatever you want.
Once he goes screaming from the room, you turn of the lights, grab your things, and try to sneak out past him and accomplish your mission.
It'd obviously require a lot of fine tuning, but I love the idea of using theatrics to your advantage, almost like an invisible batman.
