PS3- Dark Sector

The game is set in the fictional Eastern Bloc country of Lasria, and centers on protagonist Hayden Tenno, 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.
n Dark Sector, gameplay revolves around the use of the Glaive, a tri-blade throwing weapon similar to a boomerang which returns to Hayden after each throw. The Glaive can be used for long-distance combat, solving environmental puzzles, and picking up in-game items. When in close proximity to an enemy, context-sensitive actions may appear, allowing the player to execute enemies with "finishers". Enemies also hold onto Hayden while attacking, and the player must rapidly press a randomly prompted button to break free.
Environmental puzzles in the game usually focus upon capturing various elements (fire, electricity, or ice) with the Glaive.
Hayden's health is shown by the screen flashing red when he takes damage, as well as an indicator showing the attacker's position. If Hayden takes too much damage, the flash speed will increase, and a heartbeat will be heard, indicating Hayden is "bleeding out".
