In Game: Infiltration training takes over in your reactions and you look up. You see a recess in the ceiling in which there appears to be some form of either water sprinklers or halon type nozzles for fire control. There is room for you to jump up into the recess, since you've been taught how to do so. Also you've been taught how to stay in place by holding on to the sprinkler/nozzle head and bracing your feet to either side into the sides of the recess, thereby hiding from view like a wall crawler. Your instincts tell you to jump up now!
