It is officially the fall season in the northern hemisphere, and that means that Halloween is approaching. Mobile game giant Scopely has announced how it’s celebrating, and that includes crossovers with KPop Demon Hunters and Ghostbusters in the uber-popular mobile game Monopoly Go. The “Monster Mash” season, as it’s called, runs September 23-November 25. During the event, players can take part in themed minigames and “immersive adventures” featuring Huntr/X and the Saja Boys from KPop Demon Hunters.
