The Mound: Omen of Cthulhu Release Date - Launch, Price and Editions

The Mound: Omen of Cthulhu was released on Steam on Jul 15, 2026. The store data behind the listing marks the title as already out, with no coming soon flag, and the page sells it as a finished game rather than an Early Access build.

The published release date

Jul 15, 2026 is the only date the official listing gives, and it is attached to every purchasable entry on the page. There is no separate launch window for a console version, because no console version is published.

The release sits inside a crowded month for co-op horror, which is why the store page leans on its checklist features: the title of the first store section is about the four-player party, not about the jungle.

Price and editions at capture

Two entries were on sale at the time we captured the store data, and both carried the same 20 percent discount.

Entry	List price	Price at capture
The Mound: Omen of Cthulhu	$29.99	$23.99
The Mound: Omen of Cthulhu - Deluxe Edition	$39.99	$31.99

The listing does not describe what the Deluxe Edition contains beyond its name, so the difference between the two entries is not stated here.

The trailers published with the launch

Three videos ship with the store page, and the listing names each one.

• Launch Trailer, the release video attached to the page.
• Gameplay Overview Trailer, the walkthrough-style video.
• Ready Your Expedition, the preparation-themed video.

The store page published five screenshots alongside them, and it also carries two Steam content descriptors with the developer note that the game features intense violence, blood and gore. That note is part of the launch listing, not a post-launch addendum.

Five screenshots is a small gallery for a four-player co-op release, which is part of why the video set carries more of the explanation than the images do. Between them the three trailers cover the reveal, the systems overview and the preparation loop aboard the galleon.

DLC, demo status and what is not dated

Four DLC appids are attached to the product, and the store page does not publish readable names for them in the data we captured. There is no demo entry, so there is no trial version to check the game against before buying.

The launch listing also arrived with its full rating set already attached: 18 from USK, PEGI, DEJUS and the German scheme, an ESRB M and a Taiwan R, on top of the two Steam content descriptors. For a first-person horror release that is a complete paperwork trail on day one, and it is why the store page shows a content warning rather than a mild rating.

What is missing is any post-launch date: no roadmap, no content update schedule and no console window. The listing stops at the launch itself.

The systems behind a run are on How It Plays, and the build and specs are on Availability.
