You run inside the building, give the man your water, only to find out that he was an accomplice with the combine, and that there was a group of CP waiting inside.
You are immediately stunned, and cuffed and taken into a Combine APC.

You are allowed to keep your
Medical Kit, and the Combine APC begins to drive off.
You are stunned again, forced to sleep.

You awaken inside of a Combine High-Security cell. There is a sink, and toilet in the cell.
In front of you, on the fence to the right, you can see an entirely empty Civil Protection suit. Apparently, it's female.
On the side, it has a lock disabler. Maybe you could use this to your advantage?
You have nothing to grab it with, though..
In front of you is a gate, tightly locked.
Behind you is a bench. There is an item on it.
To your right is a wall.
To your left is more cell, with a sink and toilet. There is a string on the sink.
