Deus Ex: Invisible War Hints

I was walking through one of those doors that take you to another area, while i had thermal masking on. I was low on bioenergy and when i got out it said i had run out of bioenergy but i was still masked. I can walk past any bots of camera and they cant see me no sh!t
So yeh i think thats pretty cool try it when you have low bioenergy and just walk through 1 of those doors.
