Club M, the "M" possibly standing for "Madness", is a rave/disco party in the Madness Combat series, either as a by-product of the Improbability Drive or as an event organized by and for the A.A.H.W.. It first appeared in Madness Combat 4: Apotheosis as the main building where the fighting occurred. Hank killed many guards and a single 1337 agent before entering the rave, where DJ Tricky was performing. In Madness Combat 5: Depredation, a similar building fell from the sky onto Sanford and Deimos in a car when the Improbability Drive was activated on Tricky.
