FromSoftware may have another unexpected project in the works if a new rumor is accurate, with an anonymous claim saying the studio is preparing a pirate-themed dark action RPG called Cerulean Onslaught.
The report says the claim originated on 4chan and was later shared on Reddit, so this should be treated as unverified unless FromSoftware, Nintendo or another official partner confirms it. The rumor alleges that players would sail across the ocean, explore islands and use a ship as a central hub. It also claims the game could be announced at Summer Game Fest, which is scheduled to air live on June 5, 2026.
The most surprising part of the claim is timing. According to the report, Cerulean Onslaught could launch as early as August 2026, which would put it ahead of FromSoftware's already announced Nintendo Switch 2 exclusive The Duskbloods. Kadokawa's announcement describes The Duskbloods as an online multiplayer PvPvE action game for up to eight players, with a worldwide 2026 release window.
Why this rumor is getting attention
A pirate action RPG would be a sharp turn for FromSoftware, even after the studio's recent experiments outside the classic solo Soulslike mold. Elden Ring Nightreign reworked Elden Ring into a standalone co-op survival action game, while The Duskbloods is being positioned around competitive and cooperative online multiplayer on Nintendo's new hardware.
The claim also lands during a busier year for pirate games than usual. Ubisoft's official site lists Assassin's Creed Black Flag Resynced for July 9, 2026 on PlayStation 5, Xbox Series X|S and PC, bringing one of gaming's best-known pirate adventures back just weeks before the rumored FromSoftware date.
Still, there is no official Cerulean Onslaught announcement, no confirmed platform list and no verified media for the alleged project. The idea of FromSoftware building a ship-based dark RPG is easy to imagine, but the sourcing makes caution essential. Until a real reveal happens, this is best read as a specific rumor around a major studio, not a confirmed addition to FromSoftware's 2026 slate.
