Story
You play as a Chaos Insurgency spy dressed up as a Level 4 researcher. Problem: you lost your keycard on the way in. Now you're hunting keycards around the facility like it's your first day again.
You came in through Gate B to grab intel, steal some classified docs, and get out. Halfway through, you find a room where the floor just ends. Nothing but void beyond it.
The floor ends. Beyond it is void. You step onto it anyway.
