ARC Raiders The Clean Dream: Spaceport Tunnels and Maintenance Bunker Guide

Complete With A Trace, then make sure you can access Spaceport and The Blue Gate. Nothing has to be carried out of either raid, so a free loadout is sensible.

The Spaceport half uses the same Launch Towers tunnel network as Switching the Supply, which makes the route much easier if you already know that entrance.

The easiest tunnel entrance is the large collapsed concrete hole southwest of the Launch Towers. It drops directly into the underground network and is the clearest landmark to use.

1. Move southwest of the Launch Towers until you see the large collapsed concrete opening.
2. Enter down the concrete slope into the tunnel network.
3. Use the smaller perimeter structures with ladders only as alternatives if your approach to the main opening is blocked.

The tunnels are dark and enclosed, so expect short sightlines and check corners before stopping at interactables.

Search four containers while you are inside the Spaceport tunnels. Current quest information does not establish that four fixed, unique containers are required, so treat any clearly searchable tunnel containers as your targets and watch the objective counter after each interaction.

1. Stay in the underground tunnel network beneath the Launch Towers.
2. Search containers one by one and confirm the quest counter increases.
3. Stop after the fourth registered search and move to the Filtration System.

The Filtration System is close to the collapsed tunnel entrance. After entering by the concrete slope, double back and look to the right for the large labelled tanks.

1. Enter through the collapsed concrete opening southwest of the Launch Towers.
2. Double back after the slope and look right into the nearby machinery area.
3. Approach the large tanks until the monitor prompt appears, then complete the interaction.

Once the monitor action registers, the Spaceport half is complete and you can redeploy to The Blue Gate.

The Maintenance Bunker is southeast of the Checkpoint POI beside the Overlook Airshaft extraction. Use the Airshaft as the main anchor because it places you directly beside the bunker approaches.

1. Reach the Overlook Airshaft area southeast of Checkpoint.
2. Look beside the stairs leading toward the ENELICA Tower and Airshaft for a small square opening with a ladder.
3. Climb down the ladder into the bunker, or use the tunnel door on the side of the mountain as an alternative entrance.

A Rocketeer commonly patrols the area, so clear or avoid it before committing to the ladder. The nearby ENELICA Tower may also be useful if you are working on Paving the Way.

The Purification System is on the lower level inside the Maintenance Bunker. From the main interior route, look for the room with two large cylindrical tanks and machinery.

1. Enter the bunker and take the first practical route toward the lower machinery level.
2. Find the room with the pair of large tanks on the lower floor.
3. Approach the right-hand tank until the monitor prompt appears, then complete the interaction.

The blueprints are in an Admin Room inside the Maintenance Bunker. After monitoring the Purification System, continue through the bunker into the office/admin area and look for the blueprint interaction.

1. Leave the purification machinery room and continue through the bunker interior.
2. Enter the Admin Room and locate the blueprints.
3. Photograph the blueprints to complete the quest immediately.

You do not need to extract for the quest to count, although the Overlook Airshaft is close if you want to keep your raid loot.

Outstanding Balance unlocks after The Clean Dream. If it is missing from Apollo's available quests, finish The Clean Dream first, then return to Apollo and check the newly opened quest.
