Hui Sing-Yue

A crime / revenge movie loaded with gory torture sequences, including acid in the shower, a pick-axe killing and a lovely scene where a man is tied to a cross and killed with the titular critters. Scenes from this later ended up in the IFD / Godfrey Ho mishmash Majestic Thunderbolt (1985).

Taiwanese movie

Two unlikely friends cross paths and join forces after they come in possession of a map that many are on the lookout for. How will they defend themselves against an army of assassins that are also after that map in this Game Of Killers?
