Monopoly Go Monster Mash: KPop Demon Hunters and Ghostbusters from September 23 to November 25

The update includes crossovers with KPop Demon Hunters and Ghostbusters. The KPop Demon Hunters content brings back Huntr/X, the Saja Boys, Rumi, Mira, and Zoey, along with the songs "Golden" and "How It's Done."

Scopely is also adding Halloween mechanics, including Luck-O-Lanter and a dice duel. The company also mentions a Discord community vote feature, but does not say exactly what players will be voting on.

What happened

Scopely has announced Monster Mash as the new seasonal event for Monopoly Go. The season begins on September 23 and ends on November 25, keeping the game in a Halloween and autumn theme for more than two months. The announcement is part of the company’s seasonal rollout as fall begins in the northern hemisphere.

The biggest addition is a double crossover. For KPop Demon Hunters, Scopely is teasing content centered on Huntr/X and the Saja Boys, plus the characters Rumi, Mira, and Zoey. The songs "Golden" and "How It's Done" are also part of the update. The available information also mentions themed minigames and "immersive adventures" tied to the crossover, though the exact format of those features has not been detailed.

Monopoly Go is also getting Ghostbusters content. Scopely says the update includes Ghostbusters themes for vehicles, locations, and characters, along with the Proton Blaster. That ties two different licenses into one seasonal update, with one collaboration focused on a music-and-animation franchise and the other on a classic film series.

The update also introduces new seasonal mechanics. Luck-O-Lanter lets players collect sweet treats from the board, while a dice duel decides who gets the higher roll and can trick-or-treat the opponent. Scopely also mentions a Discord community vote feature, but the available information does not make clear what that vote will decide. The source material also refers to new themed collectibles available through the Blocks Boutique shop, though not all individual items have been listed yet.

Background

Monopoly Go is a Scopely mobile game that regularly rolls out limited-time seasons and collaborations. With Monster Mash, the publisher is tying two licenses into one seasonal update: KPop Demon Hunters and Ghostbusters. The timing lines up with autumn and the run-up to Halloween, a period when mobile games often lean on temporary themed events.

For KPop Demon Hunters, Scopely specifically names Huntr/X, the Saja Boys, Rumi, Mira, and Zoey. The songs "Golden" and "How It's Done" are also mentioned in the announcement. The source material also points to themed minigames and immersive adventures, suggesting the crossover goes beyond cosmetic additions. The official Monopoly Go video titled "KPop Demon Hunters comes to Monopoly Go" confirms that this collaboration is central to Scopely’s seasonal messaging.

For Ghostbusters, the update appears to include a broader set of themed additions, including vehicles, locations, characters, and the Proton Blaster. The announcement also names the Blocks Boutique shop as the place where new themed collectibles will be available. That suggests Scopely is spreading the seasonal content across multiple parts of the game, with both event mechanics and collectible items. However, the available information does not say how many collectibles are coming or how long each part of the crossover will remain available within the full September 23 to November 25 window.

The combination of KPop Demon Hunters and Ghostbusters makes Monster Mash one of Monopoly Go’s more notable seasonal updates in 2026. Scopely is clearly positioning it as a Halloween event, while using two different entertainment brands to carry the season’s content. The source material does show which franchises, characters, songs, and mechanics have been announced, but not the full details of the Discord community vote feature or the exact outcome it will determine.
