1001 Video GamesMaximo: Ghosts to Glory appears in the book 1001 Video Games You Must Play Before You Die by General Editor Tony Mott.
ExtrasAs a promotional item for the game's release, free pairs of heart-patterned boxer shorts, the kind Maximo wears underneath all that armor, were given away prior to the game's release by certain retail outlets.
ReferencesDuring the course of the game, you can buy different kinds of boxers (such as cow spots, heart prints, etc.) One of the kinds of boxers you can get is a "POW" boxer. POW was a power-up in classic Capcom games and can be seen in such games as 1942, Exed Eyes, and Side Arms Hyper Dyne.
