What is The Mound: Omen of Cthulhu?
ACE Team — the Chilean studio behind Zeno Clash and Rock of Ages — is the developer, with Nacon handling publishing. The premise pulls straight from H.P. Lovecraft: a group of explorers push into a jungle in search of treasure, but the land itself is corrupted. The deeper you go, the more reality warps around you. It's an online survival horror co-op game built for one to four players.
Gameplay
The core loop is cooperative survival under mounting cosmic pressure. Up to four players coordinate resource management and navigation while the environment increasingly fights back — not just with enemies but with the kind of psychological horror that H.P. Lovecraft used as his primary weapon. ACE Team describes forces beneath the mound that "begin to distort reality itself," which suggests the horror isn't purely combat-based. Expect mechanics that target coordination and perception as much as health bars.
ACE Team has form with weird, layered atmospheric design — their games tend to reward players who pay attention to the environment. Whether the mobile co-op can replicate the tension of the PC and console builds is still an open question, but the studio's track record earns the benefit of the doubt.
Is The Mound on Xbox Game Pass or PS Plus?
Neither has been announced. Game Pass and PS Plus availability are both listed as not confirmed at this time.
