this game is just wot the title says it's DARK
Set in the crumbling infrastructure of a fictional Soviet-bloc country in the near future, the game features both single and multi-player action, with players working their way through a world where biological weapons are a hellish nightmare, let loose on an unsuspecting populace.
The game's main character is a man named Hayden Tenno a morally ambivalent clean-up man employed by the CIA. He suffers from a real-life disease called congenital analgia that does not allow him to feel pain. On a mission in a fictional former eastern bloc nation, he is exposed to a biological compound which mutates him, dramatically changing his right arm, and giving him the ability to spontaneously grow a three-bladed throwable weapon called a glaive. the glaive is a part of his body, can be used to generate light, and can be controlled remotely by the player.
During the game, Hayden encounters others that have been similarly mutated by the compound; however, the mutation process is painful to the point that its victims go mad. Hayden's congenital analgia inadvertently protects him from this aspect of the mutation.
In Dark Sector, gameplay revolves around the use of the glaive. The glaive is a three-pronged boomerang-esque weapon which zooms back to Hayden after every throw. The glaive can be used for long-distance dismemberment, solving environmental puzzles, and picking up various items. When up close to an enemy, context-sensitive actions may appear. Environmental puzzles in the game usually focus upon capturing various elements (fire, electricity, ice, etc.) with the glaive. For example, a web that is blocking your path can be bypassed by capturing fire with the glaive and then launching it at the web to burn it down. The glaive is dual-wielded with a gun in Hayden's left hand. This allows for combos like stunning an enemy at long-distance with the glaive, running up close, and then shooting them down. The glaive can also be guided through the air, being able to kill multiple enemies. This feature is controlled via the Six-axis on the Playstation 3 and by analog stick on the Xbox 360.
Gunplay in Dark Sector is very similar to the duck-and-cover gameplay implemented in "Gears of War". The player can duck-run towards cover (a wall, pillar, etc.) and attach themselves to it. Hayden will be able to fire his gun and launch the glaive from this position while also being protected from enemy-fire. The weapon upgrade system is also similar to that seen in "Resident Evil 4". Weapons may be taken from enemies, however they will only work temporarily. There is also no blind-fire capability in the game.
Dark Sector also has an online multiplayer aspect. There are only two modes and they feature: One randomly selected Hayden character in a deathmatch against many soldier characters. Another mode involves two Hayden characters on separate teams; with one team attempting to kill the opposing teams Hayden first. In both modes, Hayden will have superior powers compared to the soldiers. Hayden will be able to become invisible, use the glaive, etc. whereas the soldiers cannot. The developer of Dark Sector, Digital Extremes, has also developed the critically acclaimed Unreal Series, well-known for their frantic and robust multiplayer.
