Deep beneath the pristine corridors of the primary decking lie the maintenance sub-tunnels—a labyrinth of low-clearance service ways now submerged in stagnant, knee-deep water. Flickering emergency lights barely pierce the gloom, illuminating forgotten engineering tools and discarded flares that hint at a hasty, panicked retreat. Tactically, this map forces players to deal with difficult terrain, drastically reducing movement speeds while wading through the murky depths. Exposed, sparking wiring hangs from the ceiling and snakes through the water, creating dynamic environmental hazards that a cunning Game Master can use to shock unsuspecting characters or ignite residual fuel. The cramped, narrow corridors create natural chokepoints and limit line of sight, a perfect configuration for tension-building encounters where hostile extraterrestrial creatures or rogue synthetics could be lurking just beneath the water's surface, waiting in ambush around the next rusted bulkhead.
