Undercover cop drama Sleeping Dogs has today launched a new DLC titled "Year of the Snake" and is set to feature a series of all-new, action-packed police missions set immediately after the main game. The DLC pack will also feature a handful of new achievements and trophies for those in need of more completion.

Year of the Snake sees Wei Shen’s story continue as he rejoins the ranks of the Hong Kong Police Department, only to be caught up in chaos. A vicious doomsday cult is taking root in the back streets of Hong Kong… the Cult of the Snake. Hell-bent on cleansing the city of its evils, they cannot be negotiated with as they pursue a murderous path to their righteous salvation.

Wei must enter a race against the clock in an explosive countdown to midnight and bring the cultists to justice before the arrival of Judgement Day. With an arsenal of weapons – including a tear gas launcher and an electroshock pistol – new outfits and abilities, Wei aims to earn back his honour with the HKPD by sabotaging the cultists’ plot to bomb, terrorize and subdue the citizens of Hong Kong.

Through several missions and optional activities, Wei will track down the Cult of the Snake’s leader and personally show him that the world is not about to end for anyone but him and his followers.

You can check out the launch trailer and screenshots below for a look at the high-kicking Wei Shen in action. Year of the Snake is available on PlayStation 3, Xbox 360 and PC for 560 Microsft Points or $6.99.
