The weapon Cleaner's Carbine, and the hat Liquidator's Lid both reference the hitman from the French film "Léon: The Professional", who refers to himself as a "cleaner", rather than a hitman. This view of himself also reflects that of the Sniper's, as he always refers to himself as a "Professional" rather than a psychopathic killer everyone sees him as. The description of the Liquidator's lid also alludes to the lead guitarist (The Edge) of the Irish rock band U2, who wears a similar tuque.
