TOOLS & ROUTES · FIELD GUIDE
Find the Hammer above the sewer route.
Checked October 16, 2026 · Full game · Source-based guide
Drain the lower route, follow the overhead pipes, then crouch-jump the raised pipe section to reach the Hammer. Marvin Tang’s October 15 release walkthrough documents this approach and the rusty gate used to leave.[1]
Follow the water, then look above it
- Turn the wheel behind the large hall’s stairs. Use the upstairs wall spike and a rope to descend.
- Below the first door, go left then right to the next wheel. Drain the passage; take the left branch and ladder to the pipes.
- After the later wheel and swim, reach dry ground and turn back toward the rusty pipe. Climb it, crouch along it, and jump while crouched over the raised section.
- Drop to the Hammer and equip it to break the rusty exit barrier.
These landmarks condense the release walkthrough; they are not an independently measured map.[1]
Already found a Hammer, but need a spare?
NPC Tips’ release-file analysis lists a Workbench recipe of 3 Iron Rods and 3 Rocks, unlocked after picking up a Hammer. This is a secondary file-analysis claim checked October 15, not our crafting test. If the recipe is absent, it does not prove your lost tool has respawned.[3]
Check the obstacle before spending more time
A key prompt is a different task from a rusty barrier. For yellow goo, follow the Pickaxe and Clay route; for roots, use the Axe route. For a rock pile, use the reported explosives search leads. The Hammer route does not establish a way to recover a tool already lost from your save.
Material: SINGLE_SOURCE for the release route. Earlier February player reports also describe sewer water and ceiling pipes, but do not count as a second release playthrough.[2]
