To earn yours, simply log into Warframe between October 2 and October 16 at 11:59 p.m. ET and claim him from your Inbox!

Heir to the twin kingdoms of Tau and Sol, Caliban debuted during The New War as the very first Sentient-Warframe hybrid. True to his origins, he's recently undergone a number of dramatic adaptations for improved playability that every Tenno should know about:

Sweeping changes have been made to Caliban's Abilities — not only to increase his overall strength but also to enhance the fantasy of wielding Sentient powers. To that end, this Rework officially formalizes Tau Damage, which Caliban now deals out extensively.

Razor Gyre has become a Status-inflicting "traversal tool," while Sentient Wrath is now more in line with the Crowd Control Abilities found among other Warframes. Casting Lethal Progeny will summon new types of Sentient allies, and Fusion Strike has seen a variety of Quality of Life improvements for a more satisfying experience.

Inspired by the fierce devotion of his mythological namesake, Caliban Orfeo channels both the Old War and the Otherworld with an impressive (but ghastly) new Deluxe Skin. Venture forth boldly in the face of death with Caliban Orfeo, or get the complete Caliban Orfeo Collection to instantly add the Seighe Venato Skin, Heurodis Ephemera and Heurodis Decoration to your Arsenal, as well. All are available now on the in-game Market.
