Two placed drain boosters sit near utility boxes; activate station infrastructure before final cleanup. Use the mission data below to check the reward, measured regions, infrastructure and target time before choosing your loadout.
Two placed drain boosters sit near utility boxes; activate station infrastructure before final cleanup.
Deployment order: Activate the station drainage infrastructure early. With fourteen completion regions, a disciplined platform-to-service-area sweep is more reliable than chasing isolated puddles.
Bring the two booster locations and utility boxes into the operation.
Locate both booster actors near their paired utility boxes.
Activate the available station infrastructure before large-scale pumping.
Observe whether both locations affect drainage; the exact stacking relationship remains unresolved.
02
Phase 2 — Stabilise the main station areas
Control deep water across the principal passenger and track-adjacent spaces.
Open drains before committing pumps.
Place pumps in the deepest persistent zones and keep outlets away from neighbouring station regions.
Maintain safe routes around the train-event area.
03
Phase 3 — Clear service and utility spaces
Move from the main floor into smaller measured sections.
Use the scan to identify utility rooms, corridors and platform-edge pockets.
Shift one pump at a time so the main station remains stable.
Use the vacuum where enclosed water is too shallow for a pump.
04
Phase 4 — Fourteen-region audit
Perform the most methodical final sweep in the current mission set.
Work through a written or on-screen region checklist.
Revisit booster and utility-box areas.
Finish platform edges, wall lines and thresholds with the vacuum and squeegee.
