Battletech: Core Rulebook

The most cohesive, approachable, and dynamic set of rules for BattleTech ever: the Core Rulebook. 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!
