The Mound: Omen of Cthulhu Platforms - Windows Build and Published Specs

The Mound: Omen of Cthulhu is available on one platform: Windows, through Steam. There is no macOS build, no Linux build and no console release published on the store listing, so availability is a short answer.

Which platforms the listing covers

The store data behind the page is explicit. Windows is true; macOS and Linux are false, and there are no separate Mac or Linux requirement blocks.

• Windows: listed, with published minimum and recommended specs and a 23 GB install.
• macOS: not listed on the store page.
• Linux: not listed on the store page.
• Consoles: no version published on the store page.

For a co-op game this matters for group planning: a four-player party all needs a Windows machine, because there is no cross-build fallback named anywhere on the listing.

Editions, price and what is attached to the listing

Two purchasable entries appear on the store page, and four DLC appids hang off the product.

Entry	List price	Price at capture
Standard edition	$29.99	$23.99 (20% off)
Deluxe Edition	$39.99	$31.99 (20% off)
DLC appids	4630450, 4630440, 4630460, 4925780	names not readable in the captured store data

The listing does not spell out what the Deluxe Edition adds, and the DLC entries have no readable names in the data we captured, so neither is described here as fact.

Controller, cloud and household sharing

The feature tags cover more than the disc image. Full controller support is listed, along with DualShock and DualSense controller support, which means the game is built around a gamepad as well as mouse and keyboard.

Steam Cloud and Family Sharing are both tagged, so saves travel between machines and the title can be shared inside a household library. Steam Trading Cards are tagged as well, which is a Steam-side feature rather than an in-game one.

The store page reported 3,186 Steam reviews at the time we captured the data, and 11 languages are listed with English flagged for full audio. None of that answers the practical platform question for a party, though: the listing never says how four players are expected to own the game, and Family Sharing is tagged without saying whether a shared library can join an online co-op session. Both are gaps in the listing rather than restrictions, and this page does not read them as either.

What the platform listing does not say

Three availability questions have no answer on the official page: whether a console port is planned, whether the game will ever ship outside Steam, and what the four DLC entries actually contain.

The first two are simply absent, and the third is present only as appids. Where the listing is silent, this page does not fill the gap.

The specs themselves are broken down on System Requirements, and the launch details are on Launch & Demo.
