Starbreeze Studios is a video game development studio based in Uppsala, Sweden.
The company was founded in 1998, under the name O3 Games. In 2001 O3 Games merged with the smaller company Starbreeze Studios who was then based in Härnösand, Sweden. O3 Games is listed on the Swedish stock market list Aktietorget since 2000 where the company stock is still publicly traded. As of June 2008, Starbreeze Studio employs 85 people.
The company's founders include people who were formerly members of the PC demoscene group Triton; Magnus Högdahl worked as CTO and was credited as Lead Engine Programmer.

The company was developing two new games, but one of them has been cancelled. The first, codenamed Project RedLime, is said to be a "reinvention" of the Syndicate franchise published by Electronic Arts. The second game based on Robert Ludlum's Jason Bourne series, was also going to be published by EA, but the project was shelved.
