BattleTech is a turn-based multiplayer game, typically played on a map divided into hexagonal grids with figurines or counters representing military units. Paper record sheets provide detailed information about each unit, including its armament, armor and equipment, and are used to track damage, heat buildup, ammunition and various other data. Players use two six-sided dice to determine variable results, such as whether a shot strikes its target and the location it hits.

Of the units represented in the game, the most common are BattleMechs, also known as 'Mechs: large, semi-humanoid fighting machines controlled by human pilots. While pre-designed 'Mechs, vehicles, and other military units are provided with the game, a complex system of design rules allows players to create their own custom units even in the introductory boxed set.

FASA Corporation published the first BattleTech game set in 1984 as BattleDroids, and throughout the '80s and '90s released a wide range of supplemental books and materials for the series. FASA ceased producing BattleTech in 2001 and sold the franchise to WizKids. FanPro licensed the rights from WizKids and under the new name Classic Battletech continued to release sourcebooks and supplements. In June 2007, Catalyst Game Labs (a subsidiary of InMediaRes Productions, LLC) acquired the license to Classic BattleTech, and has reiterated its commitment to publishing quality products. Catalyst also retained many of the staff members who worked for FanPro.^[1] Catalyst Game Labs also reverted the name back to BattleTech in celebration of the 25th anniversary of the game's release.^[2]

The latest iteration of the BattleTech rules is Total Warfare (2006), a streamlined compendium intended to integrate the numerous rules sets that have governed the series into a single, comprehensive volume that details the tournament legal and/or standard rules set for game play. Total Warfare is supplemented by six or more other books (some pending):

• 25th Anniversary Introductory Box Set, the fifth edition of the introductory box set includes all of the materials a player needs to play the game. The set includes a "quick-start" rulebook as well as a standard rulebook, plastic miniatures and record sheets of many common BattleMechs, two heavy cardboard game boards with reversible maps, and Inner Sphere at a Glance, a book detailing the game's universe.
• Total Warfare, the primary rulebook for BattleTech. It also includes the rules for playing the air combat game of AeroTech as well.
• TechManual, which presents the design rules for making custom units that comply with the standard game play rules.
• Tactical Operations, offering advanced rules and advanced or experimental equipment beyond those in Total Warfare and TechManual. In 2020, this product was split into Tactical Operations: Advanced Units & Equipment, and Tactical Operations: Advanced Rules. ^[3][4]
• Strategic Operations, updating BattleForce 2 & Aerotech 2 Revised to provide a faster-paced or large-scale version of the game as well as adding advanced rules campaign elements such as repair, customization & salvage to the tactical game.
• Interstellar Operations, advanced rules to allow the player become star lords of Succession State or Khan of their respective Clan. This is similar to previous FASA product named Succession Wars and rules found in FanPro source book named Combat Operations.
• A Time of War (BattleTech Roleplaying Game, fourth edition), describing how to create characters and run RPG missions.

FanPro intended these six books to be the official core rules set that will govern all gameplay within the BattleTech franchise, be it ground combat, space combat or role-playing. Since 2007, Catalyst Game Labs has assumed control of the franchise. The core rule plans are continuing to be refined as rule books come out.
