In Warframe built a fighting game

Studio Digital Extremes has added an unusual mode to its popular online action movie Warframe. Frame Fighter allows players to escape from space shootouts and battles on katanas and clubs and get into a real fighting game.
While in Frame Fighter mode there are only three fighters with their skill sets: Escalibur, Volt and Meg. New characters can be discovered by scanning in various parts of the game world special fragments of fighters. Access to the regime opens in the Sanctuary, where all other mini-games are also located.
