Marvel’s most reality-shattering storyline is heading to game night this summer with the MARVEL MULTIVERSE ROLE-PLAYING GAME: SECRET WARS EXPANSION, the next major tabletop release set in a universe where everything has already gone wrong.
In this new expansion, heroes and villains from across the Marvel canon clash for what’s left of existence after the Multiverse is destroyed. Under the rule of God Emperor Doom, players are thrown onto Battleworld—a single, fractured planet stitched together from broken realities. The expansion includes brand-new character sheets, playable Battleworld locations, powerful cosmic artifacts, and tools designed to turn the fallout of Secret Wars into a full-scale tabletop campaign.
Written by award-winning author Matt Forbeck alongside Alex Irvine and Marty Forbeck, with maps by cartographer Brian Patterson, the SECRET WARS EXPANSION invites players to explore wildly different corners of Battleworld. Adventures span the neon chaos of 2099, the zombie-infested Deadlands, a Gamma-ravaged Greenland, and beyond, while also diving deep into the Fantastic Four, the Negative Zone, the Guardians of the Galaxy, and the cosmic forces that define Marvel’s universe. New rules also introduce Rank X characters, allowing players to wield power on an almost unimaginable scale.
“I’ve been a fan of Secret Wars since the first one in 1984, and I’m having a fantastic time bringing all of them to life in our game,” shared Forbeck. “The Battleworld from the brilliant 2015 Secret Wars makes for the best sandbox ever. All the wildest parts of the Marvel Multiverse on one God Emperor Doomed planet!”
The 256-page SECRET WARS EXPANSION will feature a cover by Sean Izaakse and Erick Arciniega, along with a collectible convention-exclusive variant by Francesco Manna and Jesus Aburtov, available at Gen Con later this summer. When paired with the Marvel Multiverse Role-Playing Game: Core Rulebook, the expansion is designed to be an easy entry point for players ready to jump straight into Marvel’s biggest stakes.
The Marvel Multiverse Role-Playing Game lets players step into the shoes of iconic Super Heroes—or create their own—to battle some of the most dangerous villains in the Marvel Universe. With expansions like The Cataclysm of Kang, X-Men, Spider-Verse, and Avengers already available, Secret Wars adds a universe-ending chapter to the growing tabletop line.
