OVERKILL Software is a privately held company that was founded in 2009 in Stockholm, Sweden by Ulf & Bo Andersson, the former founders and owners of GRIN.
They are the creators and developers of PAYDAY: The Heist, PAYDAY 2, the upcoming Sci-fi co-op game, Storm  and Overkill's The Walking Dead, a co-op zombie survival game. Overkill was bought out and folded into Starbreeze Studios in June 2012.
Overkill Software was founded in 2009 in Stockholm, Sweden by the Andersson brothers, who have previously founded GRIN. Alongside them was Simon Viklund, who became the company's head music composer.
Their first project as Overkill, PAYDAY: The Heist (2011) was a major success for both PC and PlayStation 3, which led to a sequel, PAYDAY 2, released in 2013 to an even bigger praise. Overkill was bought and folded into Swedish game studio Starbreeze Studios in 2012.
Former Battlefield 3 and Battlefield: Bad Company 2 lead designer David Goldfarb joined Overkill for PAYDAY 2's development. In 2014 he left Overkill to start his own studio.
Their long time project Storm, a sci-fi co-op FPS, is planned to be released in 2017.
As of May 2015, the studio is now owned solely by Bo Andersson after a falling out between him and Ulf. Despite no longer being a member of the board and Creative Director, Ulf Andersson had remained on board as a primary consultant and was the voice actor for Wolf for a remainder of PAYDAY 2's support period.
After the acquisition of the PAYDAY IP from 505 Games in May 2016, studio executive Almir Listo have confirmed the development of a third PAYDAY game, to be released at an undetermined date.
