Bloodlines will combine first-person action with role-playing elements, and it is being developed by Troika Games, the studio that was responsible for the 2001 RPG Arcanum, and which was also founded by RPG veterans Tim Cain, Leonard Boyarsky, and Jason Anderson, who helped create the Fallout role-playing game series.
