Dark Sector, also stylized as darkSector, is a third-person shooter video game developed by Digital Extremes for the Xbox 360, PlayStation 3 and Microsoft Windows. The game is set in the fictional Eastern Bloc country of Lasria, and centers on protagonist Hayden Tenno (voiced by Michael Rosenbaum), a morally ambivalent CIA "clean-up man". While trying to intercept rogue agent named Robert Mezner, Hayden's right arm is infected with the fictional Technocyte virus, which gives him the ability to grow a three-pronged "Glaive" at will.
