Out Now — July 15, 2026
The Mound: Omen of Cthulhu is available now on PC (Steam and Epic Games Store), PlayStation 5, and Xbox Series X|S with full cross-play and spatial voice chat. ACE Team and Nacon ship the definitive retail build after months of demo feedback, closed beta tuning, and final sanity polish—including the Weapon Upgrade Anvil, push-to-talk, and removed mission-end timer detailed in Launch Patch Notes.
New explorers should watch the Official Launch Trailer above, then read First Expedition and Cross-Play before accepting the first Tempestad contract. Mixed-platform invites currently need the server browser. PC players hitting crashes should open Troubleshooting before reinstalling.
Launch promotions, free DLC, and patch status live on Post-Launch Updates—this page focuses on your squad's first successful extraction.

GeForce RTX owners enable DLSS 4.5 at first boot via PC Graphics & DLSS 4.5. Console squads enable performance mode for stable melee timing in fort interiors.
First Session Squad Checklist
Verify System Requirements, bind controls on Controls pages, assign lamp/salt/crossbow/musket roles on the Tempestad, and agree voice platform before disembarking. Run coastal contracts first—demo-proven pacing before logbook-unlocked fort spawns.
Practice sanity verification drills from Sanity System guide. Cross-play squads confirm Deluxe ownership before Temple of Yig briefings and game version parity before invites.
Peer-to-peer hosting favors stable broadband on the session host. Test microphone latency, disable overlays on PC if crashes persist, and extract with partial loot rather than wiping on first runs—see Beginner Tips.
Retail Versus Demo — What Unlocks Today
Full retail unlocks complete fort logbook meta, Mound-adjacent contracts, cross-play with console friends, rescue-driven character progression, and Deluxe content demo slices omitted. Demo saves are not guaranteed to transfer—start fresh unless ACE Team announces migration in Steam news.
Long-term unlock paths are documented on Meta Progression. Expect hotfixes in the first launch week targeting corruption timers, musket noise radius, and PC stability—watch Post-Launch Updates for changelogs.
Report launch anomalies through Nacon Discord and Steam discussions. Wiki articles refresh after verified retail patches—check timestamps on Guides and Gameplay pages following day-one updates.
