Look for Hidden Buttons and Passable Walls

Underkeep secret walls are a confirmed feature, including examples in the demo. The developer specifically identifies hidden buttons and passable walls as classic secret elements. Inspect unusual wall details and compare the surrounding layout with the map rather than assuming every closed route needs a key.

These secrets are generally intended to lead to optional areas or rewards, according to the developer. If your main objective is stalled, a missing secret is not automatically the explanation. Recheck the quest and visible routes before searching every wall for an invisible switch.

The official Underkeep store description also lists fake walls, hidden alcoves, and optional secrets among the game's exploration features.

Inspect the Environment From More Than One Direction

In the developer's secret-button discussion, the stated goal is to provide subtle visual or contextual hints rather than make secrets unfairly invisible. That does not mean every secret has an obvious marker.

A player in the same thread recommends actively inspecting each side of the environment, trying interactions, and consulting the map. Narrated demo playthroughs similarly describe finding small buttons after returning to an overlooked area.

Try a deliberate search instead of repeated random clicks:

  • Turn to inspect nearby wall faces rather than looking only straight ahead.
  • Examine details that seem different from their surroundings.
  • Compare the map with the passages you have actually explored.
  • Recheck the nearby layout after activating a suspicious button.

The map is useful for orientation, but it does not prove that every blank space contains a room or that every room has a hidden entrance.

Keep Secret Switches Separate From Destructible Obstacles

A hidden button, a passable wall, a breakable crate, and a pile of rubble are different interactions. In community demo playthroughs, characters attack fragile objects, discover secret buttons, and use a pickaxe on an obstacle. Those examples do not support a rule that hitting every wall will open it.

If an interaction says your bare hands are not enough or suggests a tool, check the tools you have collected. If a wall detail behaves like a switch, inspect what it changes nearby. Retaining a pickaxe can be useful, but it does not replace searching for a secret button.

No complete secret-wall coordinate list is established by these examples. Use them as a method for reading the demo's environment, and avoid importing routes from similarly named dungeons in other games.

FAQ

Are secret walls actually in the demo?

Yes. The developer confirms that both hidden buttons and passable walls already have examples in the demo.

Must I find every secret to continue the story?

The developer says secrets are not intended to block main-story progression and generally lead to optional areas or rewards.

Does the pickaxe open every secret wall?

No such rule is supported. Demo reports distinguish tool-dependent obstacles from hidden-button interactions and other secret elements.
