Chapter 4 walkthrough
The camp’s lights and the Crew Lift key are separate objectives. Solve the lighting first, then use Cavern A’s dynamite to reach Cavern B.

Finish DJ’s request
Use the counterweight control to lower the goo launch surface on the climb toward DJ. Retrieve the Allosaurus tooth from Dennis’s lair and bring it back before moving on to the Crew Lift camp.
For a retrieval task, keep two places in mind: where the item is found and where it must be delivered. Picking something up can finish the search without finishing the request.
Restore the camp lighting
Restore the camp lighting, then return to DJ and the projection area for the Crew Lift key objective. Lighting and lift access are separate tasks: the next route takes you to Caverns A and B.
Cavern A opens Cavern B
- Go into Cavern A for dynamite. Bring it back to the obstruction at Cavern B.
- Enter B and climb the spire toward the expedition remains. The lift key is beside the body high above.
- Use a fresh nearby charge for the return-route obstruction. It is separate from the charge that opened B.
Return to the Crew Lift
Return to DJ, insert the key, operate the lift and board. Leave the final route below closed if you want to discover the last escape yourself.
Show the final escape route
After the ascent is interrupted, climb quickly using the goo-wall and hanging-bar route toward the moving elevator. Complete the last lift sequence, then follow the cave passage and ladder to the surface.
On a failed attempt, identify the next reachable grip or landing before repeating the jump. Keeping a specific next target is more useful than trying to improvise the whole climb while under pressure.
