This used to be the first room that the player comes across after the breach. It consists of a walkway with a door halfway through the room, behind which a janitor and a scientist can be heard trying to escape. Shortly after entering the room, the lights start flickering rapidly before SCP-173 kills them both.
On the opposite side of the hallway is one room which contains a gas mask, a document on SCP-173, a level 1 keycard, and a few batteries. But caution should be advised, as if the player stays in that room for too long, SCP-173 will open the door to the room. If SCP-173 is disabled or captured by the NTF somehow, no NPCs will spawn, and no bodies.
