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 anyonefrom the newest players to grizzled veteransto build a force, choose a mission, grab some miniatures and start rolling dice!
