Certain Affinity is an American video game development studio based in Austin, Texas. It was founded in 2006 by Max Hoberman and a small number of other ex-Bungie employees and other industry veterans.
Certain Affinity's creation was announced in December 2006. The studio was founded by ex-Bungie employee Max Hoberman. In addition to staff from Bungie, it also includes ex-members of companies such as Microsoft, Red Storm, Origin, Electronic Arts, Digital Anvil, NCSoft, and the now-defunct Midway Austin.
The studio's first work was in creating two additional multiplayer levels for the popular Xbox game Halo 2. These maps, called "Tombstone" and "Desolation" (which comprised the "Blastacular Map Pack") were the last Halo 2 maps to be released; they are remakes of levels form the original Halo, called "Hang 'Em High" and "Derelict" respectively. They were released for Halo 2 on the Xbox Live on April 17, 2007. These maps were not released for Halo 2 Vista, but were replaced with two new maps exclusive to Halo 2 Vista: "District" and "Uplift". Certain Affinity worked closely with members of Bungie and Microsoft Game Studios during the development of these two maps.
Certain Affinity started working on another project in November 2006, which was revealed to be an unannounced original IP game in the action role-playing game genre. The game's title, platform, and release date have not yet been announced. However, Certain Affinity stated in a interview that it had "spoken with most of the major publishers and there’s serious interest, so our goal is to continue self-funding the company until we're ready to sign a publishing deal and move everyone full time onto this project."
Certain Affinity's first original game was Age of Booty, a downloadable real-time strategy game released on Steam, Xbox Live Arcade and PlayStation Network. The title was published by Capcom on October 15, 2008.
At RTX 2014, Certain Affinity showed off their involvement in Halo Master Chief Collection with the reveal of one of the six remade Halo 2 maps, Coagulation, along with a new vehicle, the Gungoose.
