The Marvel Multiverse Role-Playing Game is getting two big expansions this year, including the long-awaited Spider-Verse Expansion on March 18, followed by the Avengers Expansion on September 16. Both supplements will add tons of new rules, character-building options, and storyline ideas based on these iconic Marvel heroes to tabletop RPG, and fans eager to add some web-slinging and heroic team-ups to their tabletop sessions can preorder both hardcover books now at Amazon.The Spider-Verse and Avengers Expansions require the Marvel Multiverse Role-Playing Game Core Rulebook, which is currently on sale for $32.72 (was $60) at Amazon. The Core Rulebook is all you need to get started with the game, as it guides you through the process of creating your character and planning your own storylines for others to play through. That said, if you want to expand the core experience, you can pick up the X-Men Expansion that launched last year for just $29 (was $50). The X-Men Expansion adds a bunch of X-Men-themed rules and character-building options for creating your own custom mutant and provides information on the X-Men universe to use in your game sessions.Along with these expansions, there are also two official pre-made campaign modules available for the game. The Cataclysm of Kang includes a collection of six linked adventures designed for characters between Rank 1 and Rank 6, and pits players against the notorious villain Kang. You can pick it up for $22.12 (was $50). For something smaller, there's the Deadpool Role-Plays the Marvel Universe standalone one-shot adventure that's available for $9.29 (was $10).Marvel Multiverse Role-Playing Game BooksMarvel Multiverse Role-Playing Game: Core Rulebook -- $32.72 ($60)Avengers Expansion -- $47.49 ($50) | Releases September 16Cataclysm of Kang Adventure -- $22.12 ($50)Deadpool Role-Plays the Marvel Universe On-Shot Adventure -- $9.29 ($10)Spider-Verse Expansion -- $46.59 ($50) | Releases March 18X-Men Expansion -- $29 ($50)
