Warframe is a free to play cooperative third person looter shooter with elements of stealth. Players will take control over Tenno warriors, the ancient race that spent centuries in the cryogenic state. They found themselves at war with the three factions at once. Corpus, Grineer, and Sentients will pose a threat across the galaxy and 20 different types of missions of various difficulty levels. Players can change their Warframe, Weapons and Upgrades. Overall there are hundred of different primary, secondary and meele weapons to choose from, all of which can be aquired without paying anything, given the patience to farm for them.
Having a slow start and mediocre reviews, Warframe developers work on this game ever since, regularly adding more content, be it open world areas (Plains of Eidolon-2017, Orb Vallis-2018) or cinematic story expansions (The Second Dream-2015, The War Within-2016, The The Sacrifice-2018).
