Sleeping Dogs appears to be getting another round of downloadable content, themed after the upcoming Chinese New Year. A brief glimpse of footage and Trophy information outs it as "Year of the Snake," which just so happens to actually fall on February 10. If we had to place bets, we'd say the DLC will hit sometime around then.
The footage was discovered in the game directory after the most recent DLC release. On top of that, Trophies from Exophase (via Eurogamer) mentions "Year of the Snake" by name. It awards baubles for joining a bomb squad, defeating cultists, finding hidden collectibles, and completing side-missions.
Shacknews has contacted Square Enix regarding the DLC. Check out the footage for a look at what we can only presume are the cultists.
