ProbablyMonsters

ProbablyMonsters is an independent game developer and publisher that creates original interactive entertainment through dedicated development teams supported by shared company infrastructure. Its work spans action-adventure games, cooperative role-playing games, survival horror and other PC and console experiences. The company operates across Bellevue, Washington, and Fort Worth, Texas.

Founded in 2016 by former Bungie president and CEO Harold Ryan, the business initially developed a studio incubation model. Creative teams worked on individual projects while a centralized platform team supplied production, technology and operational support. ProbablyMonsters emerged publicly in October 2019 after several years operating in stealth.

Development and publishing

The company combines game design, level architecture, concept art, character and environment production, gameplay engineering, audio development and quality assurance. Its technical capabilities include real-time development with Unreal Engine 5. Shared infrastructure supports individual teams throughout production, while its publishing operation handles brand strategy, commercialization and global release planning.

Between 2023 and 2025, ProbablyMonsters shifted its strategy toward focused, scalable AA-plus projects and self-publishing. That transition followed the cancellation of earlier incubation projects and the expansion of a dedicated commercial organization. Its current approach combines original game development with responsibility for bringing those games to market.

The reported portfolio includes Crimson Moon, a dark fantasy action-adventure and cooperative RPG; Nekome: Nazi Hunter, a single-player third-person action game set during World War II; Ire: A Prologue, a survival horror game situated around the Bermuda Triangle; and Storm Lancers, a cooperative roguelike action game. These projects illustrate a range of genres rather than a single franchise-led development strategy.

Company development

ProbablyMonsters previously incubated Firewalk Studios before selling that business to Sony Interactive Entertainment in April 2023. Firewalk's subsequent development and release work belonged to its separate operation under Sony. ProbablyMonsters continued independently, developing its own portfolio and strengthening the publishing capabilities needed to support future releases.
