People Can Fly, the Poland-based developer which was acquired by Epic Games in 2012 and renamed Epic Games Poland, is now an independent studio once again under its original name. People Can Fly has also acquired the Bulletstorm game franchise, which it co-developed with Epic Games for Xbox 360, Windows PC, and PlayStation 3 platforms in 2011.
While now independent of Epic Games, People Can Fly is still working closely with the developer on its upcoming game Fortnite. People Can Fly is also working with Epic's Unreal Engine 4 on an unannounced game project. Indeed, the reason for the break up was because the Poland-based team wanted "to create their own games, a move Epic supports."
Formed in 2002, People Can Fly's first game was the original entry in the Painkiller first person shooter series that was released in 2004. People Can Fly first started working with Epic on the PC port of the original Gears of War game, and also worked with Epic on Gears of War 2 for the Xbox 360. After Bulletstorm was released in 2011, People Can Fly was fully acquired by Epic and handled the majority of development for Gears of War Judgement, also for the Xbox 360, in 2013.
