Warframe is a free-to-play cooperative third-person shooter video game developed by Digital Extremes for Microsoft Windows, PlayStation 4, and Xbox One. In Warframe, players control members of the Tenno, a race of ancient warriors who have awoken from centuries of cryosleep to find themselves at war with different factions.
The player may engage in PvE content through missions or PvP content through "Conclave". There are also "Quests", which are a set of PvE missions with a narrative or story behind them.
Available missions are scattered across the planets of the solar system, the moons Phobos, Europa, Lua (Earth's moon), and dwarf planets Pluto, Ceres, Eris and Sedna. Players can also access missions set in a pocket dimension known as The Void through completing junctions on other planets or through Void Fissures, small volatile rifts which react with acquirable Void Relics.
The titular Warframes are biomechanical suits that possess a set of 4 active abilities as well as a passive ability, as well as varying attributes and statistics. The player begins with a choice of Warframe among 3 initially offered. Additional Warframes can be acquired through various in-game activities, such as mission rewards, quest rewards, etc. Players can possess all Warframes in their inventory but may only equip one at a time. Warframes, as well as various other elements in the game, are highly color-customizable. New Warframes are developed and released every 3-5 months.
