An Elden Ring YouTuber just found an unused Ruined Forge dungeon in the DLC files for Shadow of the Erdtree. The dungeon looks completely complete, with enemies, items, jumping puzzles, and an interactive Forge—everything but loot.

Ruined Forges are a new type of dungeon added in Shadow of the Erdtree. They are ancient, lava-filled corridors with crumbling columns and rusted metal. There are three Ruined Forges scattered across the Elden Ring DLC map, but it turns out there's a fourth one lurking in the game files the whole time.

Dark Souls modder Grimrukh discovered the unused Forge dungeon in the Elden Ring files, and then YouTuber SekiroDubi loaded up the map to investigate. The video, posted on July 2, shows the entire unused Forge from start to finish, and it’s fascinating to see the dungeon for the first time.

It looks different than the other Forge dungeons in the DLC, lacking the giant diagonal pipe in the middle. Instead, it’s structured more like a mine from the base game, with several rocky cavern sections leading down into the ground. It’s almost entirely linear, with no branching paths, unlike most other dungeons in Elden Ring and the DLC. The most interesting part is that the dungeon features two jumping puzzles that require you to leap over broken pillars and rubble to cross pools of lava.
