The BattleTech Manual is a 104 page compilation and expansion of the rules for the BattleTech series of games: BattleTech, CityTech, and AeroTech. Considered the final version for these games, the included rules take precedence over any previous rules.
Some rules have been clarified or slightly modified in this manual.
Additionally, there are new rules covering a wide variety of equipment including VTOLs (helicopters), conventional aircraft, fortifications, minefields, naval vessels, and special weapons.
Many of the rules in this book are similar to those in MechWarrior. Players wishing more realism should use the rules in The BattleTech Manual, while players wishing a quick system should use MechWarrior.
