Dark Sector (Xbox 360, 2008)

Overview
Take the idea of a mutating virus out of Resident Evil, the graphics and controls from Gears of War and use the idea of The Glaive from the movie Krull and you've got Dark Sector. While on a mission CIA Agent Hayden Tenno becomes infected with a devastating virus that warps a person's body and normally drives them mad from the pain. However, because he was born with a condition rendering him unable to feel pain he is unaffected by the madness and is able to use the abilities gained from the virus.

Gameplay
If you've ever played Gears of War, from the onset of the game you will immediately be able to see and feel striking similarities. Whether it is the roadie run, attaching yourself to cover, vaulting over obstacles, firing from behind cover or the ability to heal by staying out of fire; all the ingredients are here.
Dark Sector sets itself apart from the rest of the third-person shooter games by employing the Glaive, which is a three-bladed boomerang that he can generate from his infected arm. Players can throw the Glaive at enemies, but more importantly they can hold down the RB to adjust it's direction slow motion in midflight to hit multiple enemies or aim for headshots. The Glaive can also become frozen, on fire, or electrically charged to not only do more damage to enemies, but to also solve various environmental puzzles that the player will be met with during gameplay.
Hayden also has access to the use of various guns, such as pistols, rifles and shotguns. A black market dealer is also located at various places throughout the game, allowing Hayden to purchase new weapons or upgrade existing ones. Hayden may also pick up and use enemy weapons against them, however these will explode after a few moments because they are encoded with a self-destruct chip that can detect when used by an "infected person", forcing you to rely primarily on your own arsenal and Glaive.

Graphics
The whole game looks very polished with character models and environments rendered beautifully and combat looking sweet with decapitations, dismemberments and loads of blood.

Controls
If you have played any third person game they will be sort of similar to Gears of War and games like 50 cent: Blood on the Sand. Holding down the A button will cause Hayden to "roadie run", L trigger zooms just like GoW, and the X button reloads.

Sound
Pretty spooky and appropriately atmospheric. It's quite unnerving to play this game with the surround sound up and the lights off because of the moans and groans of the infected. The voice acting also good, specifically with Hayden being voiced by actor Michael Rosenbaum.

Multiplayer
Dark Sector features two modes of multiplayer, Epidemic and Infection. Offering for up to 10 players to battle on five maps.
Epidemic tasks two teams against each other with one player on each side assuming the role of Hayden, with both sides attempting to eliminate the other team's Hayden character.
Infection on the other hand allows for a free-for-all battle with one player assuming Hayden's role. When a player kills the Hayden character they will become Hayden next and the process continues.
In both gametypes the Hayden character has maxed out abilities while other players run around as generic soldiers with only a firearm and some explosives to use.

Conclusion
IMHO, worth it for third person shooter fans. Enjoy...
