The supported historical weapon landmark is the older demo room with a nonworking firearm, an adjacent repair item, and an explosive-barrel obstacle. Repairing that gun enables the player to shoot the barrel and progress. No complete current-build weapon-location list was verified. This page does not claim pickup coordinates or an exhaustive arsenal route.
The opening firearm landmark
The old Steam discussion identifies the unusable gun and nearby repair resource in the same room. An independent 2025 preview corroborates that repair-teaching obstacle. Together, those accounts support a recognizable historical landmark. They do not supply a complete navigation sequence from every possible starting point or prove the arrangement survives unchanged in the latest build.
The Trench Gun name does not locate its pickup
November 2023 official notes identify the Trench Gun and explain its durability exception. An older developer reply also discusses that weapon. Neither source gives a verified pickup coordinate. They also do not prove that every early-firearm reference in another source names the same item.
Modifications are not spawn locations
The September 2026 progression explanation confirms weapon modifications as a separate upgrade channel. That establishes a system, rather than a map of weapon placements. The planned Early Access promise of access to weapons likewise does not reveal where each one is obtained. It cannot be turned into a catalog of invented pickup routes.
Use this landmark within its historical scope
If the room matches your older demo, the repair guide explains the supported use case. For the broader opening context, see the walkthrough starting guide. The research does not establish every weapon's prerequisites, missable status, or later location. This limited page is excluded from search-engine indexing pending a verified equipment route.
