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.

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!
