Development

The origins of Warframe came out of Canadian studio Digital Extremes' original vision for their previous game Dark Sector. Prior to that point, Digital Extremes was known as a work-for-hire studio, working alongside other studios to help complete development; this included working with Epic Games for Unreal Tournament (1999) and its sequels Unreal Tournament 2003 and Unreal Tournament 2004. Epic had looked to bring Digital Extremes into their studio, but found there would be issues with the Canadian government that interfered with the merger, and the studios agreed to go their separate ways. Wanting to establish themselves as a lead studio, Digital Extremes came up with the idea of Dark Sector, which they first announced in February 2000, describing the game as combining "the intense action elements of Unreal Tournament with the scope and character evolution of a persistent online universe". In early interviews, Digital Extremes said that the gameplay for Dark Sector would have had players as bounty hunters and assassins in a dark science fiction setting, with each character having a bounty on their head, making them targets for other players.
