Zack Palm from 2P.com: The game is a Third Person Shooter, and you are a Tenno. The Tenno are ancient warriors that have been awoken from cyrosleep that are activated to go and fight in a war to save Mankind against the Grineer and Corbus. The gameplay can either have you, or up to four other players playing on mission around the galaxy to help free sections that have been taken over by either of the hostile factions. This is only the basic concepts. If I were to associate Tenno, I'd categorize them as futuristic-ninja fighters. These fighters are equipped with suits dubbed 'Warframes' that have special properties that give them the edge in a fight.

MMO veterans Jack Emmert and Greg Street explain why the ‘Warframe model’ of starting small is the path for future Western MMO development.
"Digital Extremes held its first Devstream of the year and revealed Warframe on Android’s release date, Wednesday, Feb. 18, as well as the game’s next update." - Digital Extremes.
Warframe is many things to many players (whom we call Tenno).
Clad in armor of untold power, they cycle between war and grace in a solar system paralyzed by conflict. Always adapting, evolving, becoming more.
Enemies abound here, from footsoldiers to sprawling leviathans. They will fight you on land, through the skies and in the stars above. Even beyond in the great unknown.
But with your Arsenal, your Abilities, and your potential, there's nothing that can stop you.
