Square Enix has offered new information for the new DLC.
The Year of the Snake consists of the following packs: The Movie Masters pack includes three new outfits and the Law Enforcer pack contains two cop outfits, a new weapon and five police vehicles. The Wheels of Fury DLC gives Wei Shen access to a weaponised supercar, the DZS-90. Completing the missions outfits the car with upgrades that include firepower and armor. The Monkey King pack turns Wei Shen into Monkey King, giving him a character specific vehicle, and a two-handed staff used to fight the demons of the Hong Kong underworld.
Here's the full description from Square Enix:
Wei Shen’s story continues in Year of the
Snake as he rejoins the ranks of the Hong Kong Police Department in a
series of new missions set immediately after the main game. A vicious
end-of-the-world 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 path to their righteous
salvation. With an arsenal of weapons, including teargas guns and
electroshock pistols, new outfits and abilities, Wei must enter a race
against the clock to bring the cultists to justice before Judgment Day.
