Your next objectives

  1. Use containers and gantries to understand the freight-yard route.
  2. Listen for the Allosaurus and watch its movements before crossing exposed areas.
  3. Move through the train tunnels, linking running jumps into climbs.
  4. Locate and install all four fuses in the rail-cavern panel.
  5. If a fuse fails to register, check that the game is updated; patch 1.0.9 addresses a four-fuse issue.
  6. Follow the opened route and check for the Allosaurus tooth story item.

Codes in this level

No keypad is listed in this first-edition route for this level. Focus on the movement and objective sequence rather than searching this guide for a new number.

Four-fuse troubleshooting: patch 1.0.9 documents a fix affecting the four-fuse sequence. If progress fails after installing the fuses, check your game version and the developer’s patch notes. We have not reproduced the issue or tested the patch ourselves.
