The Darkness II and Star Trek developer Digital Extremes has announced that its free-to-play shooter Warframe has seen over one million players register since the game went into open beta two weeks ago.
The shooter had been in closed beta since October 2012, but Digital Extremes switched to an open beta during the week starting March 18.
Warframe is a sci-fi themed third-person shooter which sees groups of four players work together to dispatch waves of enemy troops. The game recently saw its 7.0 update, where it added new characters, abilities, and levels.
Warframe is currently in open beta on PC and Steam. For more information on the game, check out GameSpot's previous coverage.
