Neither Square Enix nor United Front Games have announced another add-on for Sleeping Dogs, but that hasn't stopped a trailer for the content leaking online.

Spotted by Eurogamer, the teaser trailer for "Year of the Snake" (seen below), was reportedly discovered in the files of Sleeping Dogs' last bit of downloadable content. PlayStation trophies for the content have also surfaced online, which is usually an indication of an impending release or announcement.

The trophies allude to bomb squads and cultists, some of which may appear in the small amount of footage leaked. Until Square Enix has more to say about this supposed DLC, we'll just have to wait and see what lies ahead for Sleeping Dogs.
