Mutant Arm Studios

Mutant Arm Studios was an independent video game developer based in Bend, Oregon, focused on original AAA games for PC and console. Its capabilities spanned game design, prototyping, software engineering, combat and systems design, level design, environment and character art, and UI/UX engineering.

The team's origins trace to a cooperative first-person shooter prototype group in Carlsbad, California, which disbanded in mid-2018. Members subsequently relocated to Oregon to establish the studio, with hiring and development beginning in 2019. Its development team brought together experience from established game companies across design, engineering and visual production.

The studio's principal known project was Project Inferno, an unannounced original game built in Unreal Engine. Artists described it as a team-based pulp adventure roguelike shooter with an interwar dieselpunk aesthetic. The project combined the studio's original IP ambitions with its work in combat systems, environments, characters and interface design. It remained unreleased.

Mutant Arm worked with an unannounced major AAA publishing partner, but funding for the project fell through. The company laid off 31 staff members on January 31, 2023, and ceased operations in early 2023. Project Inferno was cancelled as a result of the shutdown.
