Expected release on September 16th, 2026

Building on the critical and commercial success of the BattleMech Manual, a half-year of public playtesting brought forth the most cohesive, approachable, and dynamic set of rules for BattleTech ever: the new Core Rulebook.

Thanks to the support of the Catalyst Demo Team Agents and the wider BattleTech community, the Core Rulebook also contains a comprehensive Missions section: a shared, fundamental framework allowing players to easily create a huge variety of BattleTech games.

This flexible toolbox allows for everything from quick pick-up games to epic clashes, and makes it easy for anyone—from the newest players to grizzled veterans—to build a force, choose a mission, grab some miniatures and start rolling dice!
