Starting Location: The Underpass Resonant Quest
You reach The Underpass as part of Main Quest: Recursions and Iterations. After unfogging the map, you will see “The Spire” text when zooming in on the map. Stand north of The Spire and you’ll see an “eye” icon you can inspect with L1/LB, this will add the quest to your quest log. Or you can simply climb The Spire to start the quest.
See Where the Spire Leads
To the left of the fast travel door, use Gravity Shift ability to climb up the side of The Spire (the red blocks).
At the top of The Spire, defeat the enemies to open the blocked path forward (it will turn from red blockage to a bright white light). Go through there to reach the Astral Plane.
Investigate the Astral Plane
On the Astral Plane climb up, then jump over to the side of the floating path and immediately use Gravity Shift to latch onto the wall. Then you can walk up.
At the end of the path you’ll reach a locked door. You must jump to the 3 flying islands around the area, each has a key at the end. You need all 3 keys to open the doors to the Resonant. You can collect the keys in any order.
The first key is on the island directly across from the locked door (where you first climbed up, other end from the door).
The second key is on the island to the right of the door.
The third key is on the island to the left of the door.
Kill the Astral Plane Resonant
Once you have all keys, open the doors and you’ll reach the boss. Defeat the boss and then use the button prompt to finish it off. Afterward you can pick from two Abilities Spike & Astral Rebuke, but you can change these anytime later in The Gap by interacting with the Mural.
This finishes The Underpass Resonant in Control Resonant.
