The most interesting of the bunch is the Zodiac Tournament Pack, which adds an entirely new hidden island off the coast of Hong Kong. There, Wei will face a tournament to the death complete with new enemies and bosses, new story cutscenes, two unlockable outfits, and various new fighting moves.
Other packs include the Drunken Fist pack, which unlocks the alcohol-fueled fighting style, and the Gangland Style pack, which lets you get a tattoo and buff to dress like the Japanese Yakuza, Russian Mafia, or Maori Mongrel Mob.
The Square Enix pack gives you outfits based on Hitman, Deus Ex, and Just Cause. Agent 47's outfit provides reduced police attention and a silence Silverballer, a Sarif Industries armor reduces gunfire damage by 33% and grants you a futuristic combat rifle, and Rico's outfit lets you jack vehicles from a distance and fire a pistol with explosive shells.
Finally, the Dragon Master pack compiles the pre-order packs together, or they can be bought separately. That one will be available first, starting tomorrow, and dates for the other four packs haven't been detailed yet.
