Secret 6

Secret 6 is a game co-development and art outsourcing studio founded in 2005. Its work spans AAA asset production, game engineering, animation, real-time visual effects and quality assurance. With its principal production operation in Metro Manila and executive and client-relations operations in the San Francisco Bay Area, the company supports international developers and publishers across console, PC, mobile and virtual reality projects.

Art and development capabilities

The studio produces characters, creatures, environments, weapons, vehicles and props. Its 3D production services cover high- and low-poly modeling, sculpting, retopology, physically based texturing and level dressing. Its 2D teams create concept art, key art, interface assets, illustrations and sprite animation, while animation specialists handle character and creature animation and rigging.

Secret 6 also provides in-engine particle and shader effects for gameplay and cinematic sequences. Its engineering work includes gameplay programming, development tools, full-cycle game production and platform porting, with Unreal Engine and Unity among the supported engines. Testing services encompass functionality, regression, compatibility and compliance, alongside localization support.

Production experience

The company's credited projects include The Last of Us Part I, The Last of Us Part II, Cyberpunk 2077, Shadow of the Tomb Raider and Uncharted: Legacy of Thieves Collection. Its contributions range from environment and character art to weapons, props and other production assets. Alongside external development work, Secret 6 developed its own three-versus-three first-person shooter, Project Xandata.

Initially focused on outsourced 3D art, the company added dedicated 2D concept art and game development divisions in 2009, expanding its scope into broader production support. Catalis Group acquired Secret 6 in January 2023. Following subsequent group restructuring, the studio operates within Testronic's services group. Its Madrid operation closed in July 2025, with primary art, VFX and co-development production consolidated in Metro Manila.
