BattleTech: Core Rulebook

THE GAME OF ARMORED COMBAT

A thousand years in the future, humanity has spread to the stars and spawned titanic interstellar empires. Raids, counter-raids and even all-out invasions are nearly constant. You are the MechWarrior elite, piloting a multi-ton, towering avatar of war: the BattleMech. Your decisions will raise dynasties or topple worlds. 

Four decades in the making, the BattleTech Core Rulebook is the culmination of the shared passion, experience and expertise of millions of fans all around the world. Meticulously rebuilt into a modern presentation, it is the indispensable rules reference for BattleTech games. The Core Rulebook also adds an expansive Missions section allowing for rapid force building, mission selection, and battlefield engagement. This book is fully compatible with all previously released BattleTech maps and models, as well as nearly every previously published record sheet. 

Whether you’ve been here the whole time, you’re coming back to the game for the first time in decades, or picking it up for the very first time, fabulous, narrative-driven games await you on the battlefields of the Inner Sphere!

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!
