Digital Extremes filed a trademark for Soulframe in Europe on May 17th. The trademark seemingly hints toward a potential Warframe related game. However, Digital Extremes has yet to confirm a new game in development such as Soulframe.
Warframe is out now for PS4, PS5, Xbox One, Xbox Series X|S, Switch, and PC. The latest expansion, Angels of the Zariman, is also available now.
