The heating plant is failing, and something is in the pipes. You're not just running for your life — you're racing the collapse of the structure itself. As you sprint, the entity behind you matches your pace with deafening, rhythmic impacts that shake the floor. Stop, and the tunnel crushes you. Slow, and it catches you. Sprint through the dark, steam-choked service levels to the emergency vent before everything gives way.
