AntiMatter Games

AntiMatter Games was a UK game developer founded in Cornwall in 2013. The studio emerged from the international modding team behind Darkest Hour: Europe '44-'45 and went on to work with Tripwire Interactive on Rising Storm, a Pacific-theatre expansion for Red Orchestra: Ostfront 1941-1945.

Its work focused on tactical first-person shooters, large-scale multiplayer combat, asymmetric mechanics, realistic weapon handling, and historically grounded military settings. The team also provided co-development and external production support, including 3D art, character and weapon assets, environment work, rigging, gameplay animation, technical art, and cinematic production.

Games and production work

AntiMatter Games was the lead developer of Rising Storm 2: Vietnam, published by Tripwire Interactive in 2017. Its credited external-development work also included contributions to Tripwire's Killing Floor franchise and 3D art and asset production support for Turtle Rock Studios and 2K Games' Evolve.

Under Swedish games group EG7, the studio developed two major tactical shooter projects: '83, a Cold War alternate-history multiplayer game, and I.G.I. Origins, a stealth-FPS prequel to the Project I.G.I. series. Development on '83 was paused in 2022 while the studio concentrated on I.G.I. Origins and converted that project to Unreal Engine 5.

Closure

EG7 announced the wind-down of AntiMatter Games in May 2023 after considering alternatives including work-for-hire contracts, third-party co-publishing, and divestiture. Operations ceased during 2023, and the legal entity, ANTI-MATTER GAMES LIMITED, entered members' voluntary liquidation before being formally dissolved in October 2024.

The studio's work reflects a focus on PC and console interactive entertainment, especially tactical multiplayer games and specialist production support for larger game-development projects.
