Hidden Passages and Items

Underkeep rewards players who check more than the obvious route. The official game description confirms hidden alcoves, fake walls, puzzles, and handcrafted dungeons. It does not provide a complete list of hidden items or room coordinates, so verify each discovery in your own game before adding it to a collection guide.

Search for clues, not random clicks

Look closely at walls and objects that differ from their surroundings. Check nearby symbols and puzzle elements before moving on, and use the automap’s custom markers for anything that remains uncertain. A marker lets you return after finding a key, clue, or other condition without searching the whole dungeon again.

Keep item notes precise

When you find an item, record the visible location and the action that revealed it. Distinguish between an item found in a hidden alcove and one obtained after solving a puzzle. Do not assign an achievement, chest type, or reward to a location unless the game confirms it.

Revisit unfinished areas

Handcrafted dungeons may ask you to solve an ancient puzzle or pass through a concealed route. If a wall or object does not respond, mark it and keep exploring. Return when the party has new information or access. This method focuses on target-game secrets and avoids mixing in unrelated chest achievements from other games that share the Underkeep name.

Sweep a room before moving on. Look for suspicious walls, check side passages, and mark anything that seems to require a key, puzzle solution, or later return. Since the dungeons are handcrafted, careful observation can help distinguish a meaningful route from an ordinary dead end. Keep discoveries tied to the specific game version and area where you found them. Avoid importing chest names, achievement requirements, or coordinates from other titles called Underkeep; those do not establish where an item is located in this game.
