BattleMech Manual

The BattleMech Manual is a hardcover BattleTech rulebook that covers game rules for BattleMechs (only) in a concise and clarified fashion.

This book is not to be confused with the 1987 BattleTech Manual rulebook.

A second printing was announced on the official BT forums in December 2018, and was released in PDF on 22 January 2019. The reprint features errata corrections and further rewordings and clarifications, as well as new cover art. A third printing was released on 17 March 2020: in addition to the usual errata corrections, this printing added an index.

Description
The Manual is intended as a self-contained rulebook for players who wish to focus on BattleMech combat, with an emphasis on tabletop gameplay (as opposed to being a reference manual like previous core rulebooks). While it thus leaves out all other unit types, and was deliberately written to be as concise as possible and to eliminate rules vagaries, it is not intended to be a purely introductory product. It contains a few pieces of equipment from Interstellar Operations, many pieces of equipment taken from Tactical Operations, and a few of the optional rules found in that book and Strategic Operations. No construction rules are included. In terms of product progression, it is meant to slot in between the introductory box set (either the 25th Anniversary Introductory Box Set or its replacement, A Game of Armored Combat) and the full tournament ruleset of Total Warfare.

New rules appearing in the book are limited to simplified rulesets for fire and smoke; artillery, mines, and airstrikes; and a few terrain or weather conditions. Additionally, the BattleMech Manual features a Design Quirks section that brings together all 'Mech-based quirks published to date, updates them, adds nine new ones, and then applies the result to an included list of all 'Mech units in the game released prior to Technical Readout: Prototypes (when quirks first began being added to each Technical Readout unit entry). As such, the BattleMech Manual provides an official quirk listing for all 'Mechs published prior to TRO: Prototypes (though it only lists quirks present on every example of a machine; quirks applicable only to individual variants were left out).

While the rules were reworded and their layout changed, the base ruleset included in the BattleMech Manual matches the fourth printing of Total Warfare (plus all errata through to the June 2017 errata releases). The rules were not altered beyond the addition of the aforementioned optional simplifications.

From the Back Cover
"''
 * Standing from seven to sixteen meters tall, and weighing from twenty to one hundred tons
 * Powered by an armored and shielded fusion reactor
 * Skeleton of honeycombed, foamed aluminum core wrapped with stressed silicon carbide monofilament and sheathed by a rigid, titanium-steel shell
 * Locomotion generated via bundles of polyacetylene-fiber myomer muscles
 * Protected by aligned-crystal steel over a layer of boron nitride impregnated with diamond monofilaments
 * Mounting a swath of powerful weapons from charged particle beams to lasers, missiles to rapid-fire autocannons
 * All at the command of the noble elite, the MechWarriors

The modern BattleMech is the end result of more than three thousand years of battlefield technology development. Combining awesome destructive power and unparalleled maneuverability, the BattleMech is perhaps the most complex machine ever produced. The undisputed master of thirty-first century warfare, the BattleMech seems destined to reign supreme for centuries to come.

—Excerpts from a promotional pamphlet originally distributed by Defiance Industries of Hesperus, Lyran Commonwealth, 3007

Using the most up-to-date rules text, the BattleMech Manual has been designed from the ground up to cater to the BattleTech player wanting to engage in an all-’Mech battle. Includes a variety of optional rules, terrain and more.

Welcome to the most table-usage-friendly BattleTech rulebook ever published!"

Development Notes

 * The Catalyst Game Labs Tumblr featured a series of posts explaining the concept and some of the design steps behind the BattleMech Manual: 1 2 3 4 5
 * An article explaining what the Manual does and why was posted to the official BattleTech website in January 2017.
 * The Manual was pre-released as a Beta PDF version in January 2017. This 'Open Beta' version cost $10, but for the the first month of its release was coupled with an electronic survey that gave a $5 coupon for use at the Catalyst Game Labs webstore. Purchasing the beta did not provide an automatic free upgrade to the final PDF release, unlike previous Catalyst beta offerings. The beta closed in July 2017.


 * A follow-up article detailing some of the results of feedback collected in the Beta to date was posted to the CGL official Tumblr in March 2017. As a result of user feedback, additional advanced equipment from Tactical Operations and Interstellar Operations was added to the final release.
 * A further follow-up article published immediately following the book's final release detailed more of the specific changes made between the Beta and the final.

Errata
CGL maintains an errata forum thread for this book as well as an errata document for download from their website's Errata section.

When the first printing had sold out and a second, updated printing was prepared, Keith "Xotl" Hann offered a FDF document to go with the PDF release of the first printing that would include most of the changes included in the second printing. (Download link)
