Under development since 2000, Warframe is a free-to-play cooperative third-person looter/shooter published by Digital Extremes. In the science fiction setting of Warframe, players control members of the Tenno, a race of ancient warriors who have awoken from centuries of cryosleep to find themselves at war in a planetary system with different factions. The Tenno use their powered Warframes along with powerful weapons and abilities to complete missions. The game includes elements of shooting and melee games, parkour, and role-playing games to allow players to advance their Tenno character with improved gear. The game is supported by microtransactions that allow players to purchase various in-game items that are otherwise available through grinding.
