The Mound: Omen of Cthulhu unlocks on PS5 at 08:00 AM UTC on July 15, 2026 on the PlayStation Store, while Steam and Xbox Series X|S share the same July 15 date with no exact unlock hour listed yet.
The wait for ACE Team and Nacon‘s Lovecraftian co-op horror game comes down to one clean answer on PS5 and a fuzzier one everywhere else. The PlayStation Store puts a precise clock on the console launch, but the Steam and Xbox listings only pin down the calendar day. Here’s exactly where each platform stands so you know when to expect the download to go live.
Release times across PS5, Steam, and Xbox
| Platform | Unlock status |
|---|---|
| PS5 | July 15, 2026, 08:00 AM UTC (4:00 AM EDT / 1:00 AM PDT) |
| Steam (PC) | July 15, 2026 — exact unlock hour not listed yet |
| Xbox Series X|S | July 15, 2026 — exact unlock hour not listed yet |

What 08:00 AM UTC means for PS5 players
If you’re on PS5, the 08:00 AM UTC unlock lands in the small hours across the United States. That’s 4:00 AM EDT on the East Coast and 1:00 AM PDT on the West Coast, both on July 15, 2026. Pre-load ahead of time and the game should flip to playable at those local times without you needing to babysit the store.

Where Steam and Xbox launch times stand
The Steam store page and the Xbox Series X|S listing both point to a July 15, 2026 release, and that date is solid across every storefront. What neither one spells out is a precise unlock hour — there’s no published global launch time, rolling regional midnight, or unified UTC moment for those two platforms yet.
If you need the exact minute on PC or Xbox, the reliable move is to watch the storefront itself as launch closes in. The Steam store page typically surfaces a countdown timer in the final stretch before a release, and the Xbox store listing will reflect its own unlock behavior close to the day. Until then, plan around the date and keep an eye on the page for the hour.
Pre-load early and check the storefront countdown the night before — PS5 is locked to 08:00 AM UTC, but Steam and Xbox players should watch their store page for the exact local unlock.

Platforms, editions, and pricing at launch
| Edition | Price |
|---|---|
| Standard Edition | $29.99 |
| Digital Deluxe Edition | $39.99 |
The Mound: Omen of Cthulhu ships on PS5, Xbox Series X|S, and PC — the PC release covers both Steam and the Epic Games Store. It’s published by Nacon and developed by ACE Team, and it runs online co-op for up to four players — though cross-platform play between PS5, Xbox and PC has not been officially confirmed.
There are two ways to buy in. The Standard Edition runs $29.99, and the Digital Deluxe Edition steps up to $39.99. That extra ten dollars bundles the Lost Explorers’ Swords Pack, the Abyssal Gear Pack, the Fortune Hunters Characters Pack, a Temple of Yig exclusive mission, and the digital soundtrack — cosmetics, two more playable characters, and an added area for anyone who wants more out of launch day.
The cursed jungle you’re dropping into
Under the hood this is a Lovecraftian co-op first-person horror game with an extraction-style loop, built for up to four players online. You set out from the galleon Tempestad, sign a contract with your captain, and push into a cursed South American jungle to hunt treasure, recover logbooks from abandoned forts, and search for the titular Mound. Cross-platform play between PS5, Xbox Series X|S, and PC has not been officially confirmed, so for now plan on teaming up with friends on the same platform.
