Level 4 Walkthrough: The Deep & the Ending

Checked October 31, 2026Game v1.0.9No codesAchievement: FinallyEnding spoilers folded

Release the counterweight, find DJ and fetch him an Allo tooth, survive the attack when the guns jam, restore the crew lift camp lights, take dynamite from Cavern A to blow open Cavern B, grab the lift key at its top, then ride the crew lift up with DJ.

Heads-up: this level follows one detailed community walkthrough; we have not replayed it ourselves yet. The ending itself is folded below.

1. Blue caverns, counterweight and DJ

Puzzle menu
  1. Escape the creature through the blue cave route to an abandoned camp. Climb past the projection area using the glowing surfaces, wooden structures and goo walls.
  2. Press the red button at the counterweight to release it and expose a goo-assisted climb. If you cannot reach the first ledge, you skipped the button.
  3. Ignore the gun on this stretch; it is unusable. Follow the crying voice to DJ, who asks you for an Allo tooth.

2. The Allo tooth and the jammed guns

Puzzle menu
  1. From DJ, cross the pit on the hanging bars and follow the side passage to a small room: the tooth is there. Take the stairs outside to the projection room.
  2. After the presentation, a creature bursts through the screen. Your objective becomes “find a working gun”: the one on the crates jams, so does the one by the green-lit crates.
  3. When Jordan drops the gun, leave through the open cave passage until the encounter ends, then return the tooth to DJ.
  4. Another attack starts straight away. Run through the blue tunnels and climb out on yellow bars, goo walls and wooden ledges.

3. The crew lift camp

Puzzle menu
  1. The large camp has a locked crew lift; DJ waits at the covered controls. Talk to him.
  2. Turn the camp lights on with the switch on the wooden post outside, along the sloping path beside the buildings.
  3. Back with DJ, the new objective is the crew lift key, which is in Cavern B.

4. Cavern A dynamite, Cavern B key

Puzzle menu
  1. Cavern B is blocked. Go into Cavern A: ramps, goo walls, bars and raised platforms lead to a worktable with dynamite.
  2. Plant it at the Cavern B entrance and work the plunger.
  3. In Cavern B, bounce up, link the wallrunning panels and bars and follow the high ridge. The lift key is beside a body at the end, near the final note.
  4. The way back is a chase across wallrunning surfaces. Plant one more charge at the marked obstruction to reopen the path to camp. A plush pedestal is near this route; it is not needed for the lift.

Crew lift key: use the body and nearby note as landmarks at the top of Cavern B. This frame is after collection—the key is already in the player’s hand.

5. The crew lift

Puzzle menu
  1. Insert the key at the lift control, turn it and pull the lever. Go down the stairs under the Crew Lift sign, board with DJ and press the button.
Ending spoiler: what happens on the lift
  1. A creature interrupts the ride and forces Jordan off the elevator. The objective changes to catching it.
  2. Climb alongside the moving lift: goo-wall panels, yellow bars, winding ledges, the red suspended structure, then a cramped cave with smaller creatures.
  3. Run for the elevator when DJ calls and jump back on. A struggle plays out on the lift.
  4. At the top, follow DJ through the short dark cave and climb the ladder. The closing scene is by Stella’s car. Achievement: Finally.

There is one ending; the lead developer confirmed branching endings were cut. Finishing unlocks New Game Plus.

Quick answers

Where is the crew lift key?

At the top of Cavern B, beside a body near the final note. Cavern B is blocked: get dynamite from the worktable in Cavern A first and blow the entrance.

Where is the Allo tooth?

After DJ asks for it, take the hanging-bar route across the pit and follow the side passage to a small room. The tooth is inside; the stairs outside lead to the projection room.

Can I use the guns?

No. The first gun pickup is unusable and the two you try during the attack both jam. Run.

What happens after the ending?

You unlock New Game Plus with four amber-based modifiers. See the collectibles page.
