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.
Dark Sector received mixed to positive reviews for its visual design, originality of action and weapon-based gameplay. Many critics have compared the game to Resident Evil 4 and Gears of War, for their similar style of play and story.
