Stepping away from your typical third-person MMO experience, Warframe doesn't concentrate on PvP and it doesn't reward fastest-finger-first gameplay; instead it offers players a unique cooperative experience supported by AAA graphics and a variety of complex game systems.
Players take on the role of Warframes, powerful exo-armor that can harness the very latest combative technology to give players the ability to unleash a variety of devastating abilities. Each Warframe offers players a different play style, ranging from typical tank-type MMORPG mechanics to in-depth stealth and espionage classes.
Update 6 introduces new environments in the form of the Grineer Asteroid Base, 2 new playable Warframes and surprise acrobatic features. Prior to the release of the update Digital Extremes didn't even hint at the possibility of wall running and other acrobatic feats, making it a welcomed surprise for the players of Warframe. Players will now be able to run up walls, up and over crates and even zipline their way through the tougher parts of the level.
