The Mound: Omen of Cthulhu Extends Steam Demo After Welcoming 200,000 Players

Steam Next Fest has wrapped up, but the nightmare in the jungle is not over yet. Developer updates confirm that The Mound: Omen of Cthulhu drew more than 200,000 players during the week-long event. In response to this reception, the team is keeping the playable demo live on Steam for a little while longer.

If you missed the initial run or want another crack at surviving the depths, here is what this demo extension means as we head toward the July launch.

200,000 Explorers and Counting

Reaching 200,000 players is a notable milestone for this upcoming horror title. The demo gave players their first hands-on look at the game's core loop: navigating cursed foliage, managing team sanity, and trying to haul treasure back to the safety of the galleon.

Feedback from the event highlights a mix of frantic coordination and accidental team-killing caused by the game's central madness mechanics. If you are curious about how these mechanics function under pressure, check out our breakdown of the sanity system to keep your head straight during expeditions.

The Demo Extension: What You Need to Know

The developers did not announce a specific end date for the extended demo, stating only that it will remain active "for a little while longer."

• Where to play: You can still download the client directly from the Steam store page. If you need step-by-step instructions or tips on getting set up, see our wishlist and demo guide.
• Feedback is priority: The main goal of this extension is data gathering. The developers are actively requesting players to fill out their official feedback survey to help balance combat, adjust horror elements, and fix bugs ahead of release.
• Progress transfer: While not explicitly confirmed, standard industry practice suggests demo progress likely will not carry over to the final release, so treat these runs as pure survival practice.

Looking Ahead to July 15

With the official launch set for July 15, 2026, this extra demo time gives the studio valuable telemetry to polish the final experience.
