Revenge of the Martians
Martians return to the North Pole decades after Santa Claus defeated their earlier invasion. Santa, his daughter Sugar Plum, Billy, Betty, and loyal Elf Commandoes fight to protect Christmas and save Santa’s life. This supplement provides six pre-generated characters, new combat maneuvers and traits, and six linked battle scenarios forming a connected campaign. It also adds rules for designing and fighting with vehicles in ROLF! games.
