Atomic Mass Games

Atomic Mass Games is a tabletop game studio based in San Diego, California, and a subsidiary of Asmodee. The company became prominent through Marvel: Crisis Protocol, a miniatures skirmish game released in 2019. Players assemble teams of Marvel characters, including heroes, villains, and affiliated characters, then battle across a three-dimensional table while interacting with terrain. Unlike a traditional board game, Crisis Protocol emphasizes miniature assembly, painting, tactical positioning, character abilities, and scenario objectives. Its rules support teams built around affiliation, allowing players to create rosters connected to groups such as the Avengers, Guardians of the Galaxy, or Cabal.

Crisis Protocol was a significant early project for Atomic Mass Games because it established the studio’s identity around licensed, character-driven miniatures games. The company continues to expand the game through character packs, terrain, affiliation rules, and organized-play material. Its releases have included miniatures representing well-known Marvel figures such as Spider-Man, Captain America, Thanos, and Doctor Strange. The game’s background material draws from Marvel’s comic-book universe rather than adapting one single film storyline.

Atomic Mass Games also became responsible for several Star Wars miniatures properties formerly associated with Fantasy Flight Games. Asmodee announced in 2020 that development of Star Wars: X-Wing, Star Wars: Armada, and Star Wars: Legion would move to Atomic Mass Games. Star Wars: Legion is a ground-combat game featuring infantry, vehicles, commanders, and special forces, while X-Wing focuses on starfighter battles and Armada models capital-ship engagements. The transition made Atomic Mass Games a major steward of established Star Wars tabletop systems, requiring it to maintain existing product lines while developing new expansions and rules support.

In 2023, the studio released Star Wars: Shatterpoint, a skirmish game centered on small strike teams and cinematic confrontations from across the Star Wars setting. Its gameplay uses character teams, terrain, mission objectives, and distinctive combat abilities. The game’s focus on named characters and dramatic scenarios differentiates it from the larger-unit structure of Legion.

Atomic Mass Games has therefore built its catalog around recognizable licenses, but its work is not limited to branding. Its products depend on interconnected rules systems, miniature design, scenario writing, painting communities, and organized play. The studio’s history is closely tied to Asmodee’s broader tabletop publishing network and to the transfer of major Star Wars game lines from Fantasy Flight Games, while Marvel: Crisis Protocol remains the project most directly associated with its formation and public identity.
