Set in the far reaches of outer space during a new Dark Age, WarFrame introduces the Tenno, a race on the brink of extinction after being enslaved by the Grineer for centuries. Players enter WarFrame on the cusp of the Grineer's victory over the Tenno until they begin to arm themselves with WarFrames - an ancient exo-skeletal technology only they can operate. Hidden within the Orokin Derelicts of a lost civilization, new WarFrames lie dormant and undiscovered. These artifacts are the Tenno's only hope for survival.

WarFrame is a free-to-play fast-action PvE shooter set in an evolving sci-fi world. Some would call it MMO-Lite as squads of four players band together to advance their characters and battle the oppression of the genocidal Grineer. Throughout their combat missions, players will continually increase the power and abilities of their WarFrame and weapons. Players will raid new areas of space searching for exotic and powerful weapons and WarFrame augmentations to customize their arsenal. With WarFrame's Automatic Mission Generator, the game will offer endless replay as levels are procedurally configured for a unique raid -- every time.

WorthPlaying has teamed up with Digital Extremes to give away 500 Warframe keys, giving you a special 3-day credit booster that Doubles the amount of credits you get from pickups.

UPDATE: We've added another 500 keys!
