Chin's character is heavily inspired by Yuen Siu-tien's portrayal of the Qing Dynasty drunken boxer Beggar So (Sam Seed) from the Drunken Master film series.

There are many similarities between Psycho Soldier Team's design and characters from the Drunken Master film series. Kensou's character is possibly influenced by Jackie Chan's portrayal of Wong Fei-hung from the first Drunken Master film. Kensou's love of Steamed Buns is may also be a reference to a scene from the film where Chan's character attempts to steal food from a restaurant. Likewise, Athena's final design in the game is likely inspired by the lead female character from Story of the Drunken Master. Both characters were students of the Begger So in the films.
