Six months of DLC is planned for open-world action title Sleeping Dogs, publisher Square Enix has announced.

The first content will be available when the game hits stores this Friday, including the 80s-inspired Retro Triad Pack, a killer old school outfit with its own player buffs and funky kung-fu van.

New content packs are planned from September, beginning with a high-speed Racing Pack and an explosive SWAT Pack. Further announcements will follow soon.

"Sleeping Dogs is a game we know fans will want to keep on playing, so over the next six months we'll be creating a series of new content packs giving players everything they need to keep enjoying the game," said Lee Singleton, general manager, Square Enix London Studios. "We want to create something to suit everyone's play style from cool cars and high-speed missions to outlandish outfits and game-extending mission packs. The game launch is just the beginning."

Look out for our verdict on Sleeping Dogs tomorrow.
