You rach into your pack and withdraw a tiny bot. It has two parrallels tread underneath, with a special chemical applied that makes them stick to non-organics so long as pressure is applied. It makes the bot perfect for climbing the wall and scouting for a vent. You quickly find one and roll down through it, into the main room.
It's empty, save for a few boxes. Still, now that you're in there, may as well take a peek around before you fill that room with warm, soon to be cold bodies.
There are piles of crates, everywhere you look. Although none block the doors, and they're easily navigable by organics and machines alike, they block the light, and thus make good hiding spots. The room is empty of anything living, though, including the bio-medical shots in standard issue medpacks. Which isn't surprising; medpacks are best stored cold, since they work best when almost freezing. They even come with their own little fridge for the shots.
A quick heat-scan reveals the boxes are mostly full of insulating materals, most likely paper and plastic. some contain civilian level ammo and hunting rifles. The rifles are worse than your standard issue though, and the ammo isn't compatible with the military-grade software. Still, if you have a issue with your gun, they're deadly enough.
There are three doors. Two lead into the building (north, east) and one leads west and out, to where your squad is waiting. Your bot can still fit under the cracks in the doors, but the question is: Which one?
