cool, yea I've been thinking of doing something similar - 'Cold Reading' Blips (which would be blue instead of green) they would be placed along with the normal blips but the Alien player cannot move them - they are flipped over when Marines gain line of sight just like normal blips, but on the other side are things like crates, barrels, extra weapons, auto-defence gun turrets and 'dormant' androids (things that don't move basically)
