Yes, The Mound: Omen of Cthulhu supports full crossplay across PC, PlayStation 5, Xbox Series X/S. This means you can play with friends regardless of their platform. Cross-progression is limited — your progress only carries between some platforms, not all of them.

Partially — The Mound: Omen of Cthulhu has limited cross-progression. Your progress carries between some platforms but not others, so check the matrix above before you buy on a second platform.
Only partially, and only inside Microsoft's ecosystem. The Mound is an Xbox Play Anywhere title, which means a single purchase covers Xbox Series X|S and the PC (Microsoft Store) version, and your save carries between them. No cross-save has been announced between Steam, the Epic Games Store and PlayStation 5 — buy it there and your progress stays on that platform.
No — The Mound: Omen of Cthulhu does not offer split screen or couch co-op. To play together, each player needs their own system running the game.
No. There is no local or split-screen co-op. All four-player co-op happens online, with each explorer on their own machine.
The Mound: Omen of Cthulhu supports cross-platform co-op between PC, PlayStation 5 and Xbox Series X|S at release. Its Xbox store listing formally declares 'Xbox cross-platform co-op', and ACE Team confirmed on Steam that the game was being built with crossplay in mind. In practice that means a group of up to four explorers can be split across all three platforms without anyone needing to switch hardware.
The Mound is a purely cooperative first-person horror adventure for 2-4 players, set during the Conquistador era. You form a group of explorers, take on a contract, and push into a cursed jungle where monstrous creatures alter reality and staying clear-headed matters as much as staying alive. Co-op is online only — you invite friends or join a group from the lobby.
Yes. A single-player mode is listed alongside the 2-4 player online co-op, so you can take on contracts alone — although the jungle, and the game's design, clearly favour a full group.
The Mound: Omen of Cthulhu is developed by ACE Team (Zeno Clash, Rock of Ages) and published by Nacon. It launches July 15, 2026 on PC — via Steam, the Epic Games Store and the Microsoft Store — plus PlayStation 5 and Xbox Series X|S.
Yes. Cross-platform co-op is supported between PC, PlayStation 5 and Xbox Series X|S from launch day, so your group of four can mix platforms.
July 15, 2026, on PC (Steam, Epic Games Store and Microsoft Store), PlayStation 5 and Xbox Series X|S.
Two to four players in online co-op. The game is built around a group of explorers taking on a contract together.
Only through Xbox Play Anywhere, which shares your save between Xbox Series X|S and the PC (Microsoft Store) version. No cross-save has been announced for Steam or PlayStation 5.
Yes, a single-player mode is available, but the game is designed as a co-op experience for a group of up to four explorers.
No. Co-op is online only — there is no local or split-screen option.
