About The Irregular Corporation

The Irregular Corporation is a London-based video game publisher founded in 2015. Established alongside Mediatonic as a distinct publishing business, it focuses on simulation, management and enthusiast games made with external developers. Its work spans project financing, production support, marketing and distribution for PC and console releases.

The publisher's developer support covers milestone funding, QA coordination, localization, platform compliance, public relations and community management. Its publishing catalogue encompasses practical simulations, business management games, strategy titles and narrative adventures, with releases across PC, Nintendo Switch, PlayStation and Xbox platforms.

Publishing catalogue

PC Building Simulator became a commercial breakthrough following its Early Access release in 2018, followed by a full release in 2019. The project was developed in collaboration with Claudiu Kiss and helped establish the publisher's association with specialist simulation games.

Other publishing projects include Mediatonic's puzzle adventure Murder by Numbers, Chasing Carrots' manufacturing management game Good Company, Fireart Games' TOHU, Orbcreation's Sailaway: The Sailing Simulator and Auroch Digital's Mars Horizon. The company also provided initial Early Access support for Foxy Voxel's Going Medieval. These relationships reflect a publishing model built around collaboration with separate development teams rather than a network of internal development studios.

Group history

In 2020, The Irregular Corporation became part of Tonic Games Group alongside Mediatonic and Fortitude Games. Epic Games acquired the group on March 2, 2021. The publisher's publishing and intellectual property management operations were subsequently integrated progressively into Epic Games Publishing.

Later releases associated with Epic Games and The Irregular Corporation branding include Spiral House's PC Building Simulator 2 and Pumpernickel Studio's Touch Type Tale - Strategic Typing. Some earlier publishing relationships subsequently changed: publishing rights for Mars Horizon transferred to Secret Mode in May 2024.

The Irregular Corporation remains an active UK legal entity holding intellectual property assets and corporate rights within the Epic Games group. Its official website redirects to Epic Games, while its publisher catalogue remains represented on Steam.
