Arkane Studios is on its first full project since the excellent action RPG Dark Messiah of Might and Magic, released five years ago. Four years prior, the company released Arx Fatalis, a deep first-person RPG originally set to be a new Ultima Underworld installment.
The new work: Dishonored, a first person action title being directed by Arx Fatalis lead designer Raphael Colantonio and Deus Ex lead designer Harvey Smith, with help from Half-Life 2 level designer Viktor Antonov. Said to be about violence, infiltration, and achieving objectives, the game will be released by publisher Bethesda on PC, Xbox 360, and PS3 next year.
Unfortunately that's all we've got for now, but more information is expected to hit this month and next.
