 Many employees left Starbreeze when MachineGames recruited . Then CEO Johan Kristiansson also stepped down , and was replaced by Mikael Nemark . Nemark took the studio in a new direction . Besides focusing on AAA video games , it would also allocate resources to develop smaller , downloadable games in order to broaden the company 's portfolio . These new games would no longer use the engine created by Högdahl . In 2011 , Starbreeze announced that it was partnering with Epic Games to use their engine , Unreal Engine , for their first small titles . In 2012 , Starbreeze announced Cold Mercury , a free @-@ to @-@ play video game and a project codenamed P13 . Prior to that , Josef Fares , an award winning Swedish director , had been unsuccessfully pitching game ideas to several Swedish developers . Starbreeze was in need of new , original properties , and accepted Fares ' pitch . P13 later became Brothers : A Tale of Two Sons . Focusing on creating an emotional and " personal " experience , Starbreeze partnered with publisher 505 Games to publish the game . It was released in 2013 to critical acclaim and received numerous awards and accolades . The rights to the Brothers intellectual property was later acquired by 505 Games in 2015 . After the success of Brothers , Fares announced that he had established a new studio named Hazelight and is working on a project with Electronic Arts .
