Kaos Studios, a division of THQ, Inc. located in New York City, was formed in 2005 by industry veterans of the FPS genre. The core members of the group came from Trauma Studios, creators of Desert Combat (one of the most successful mods of all time from the original Battlefield) and the R&D team for DICE's Battlefield 2. The 75-person team includes additional members from the development teams of other acclaimed shooters, including FEAR, Medal of Honor and Doom 3.
