Previously rumored, but now official, Blacklight: Tango Down will be hitting Xbox Live Arcade tomorrow - July 7th - for 1200 
. According to the press release the game will offer 12 maps across seven game types, including four cooperative missions and "literally trillions of weapon combinations." Sounds like Borderlands syndrome.
Blacklight: Tango Down features players in a futuristic combat situation using a hyper reality visor which grants extraordinary vision on the battlefield. Combined with a in depth weapon customization system, you'll have realistic weapons with a sci-fi edge...oh...and dangly things. Because we all love dangly things.
The game is also slated to hit the PlayStation Network and PC - both of which should arrive "in the coming weeks."
