The Introductory Box Set was designed as the entry point into the game for new BattleTech players, allowing them to slug it out in thirty-foot-tall war machines known as BattleMechs. The rules provide construction rules for building or customizing your own (introductory-level) 'Mechs, and quick-start rules for vehicles and infantry for players interested in simplified combined-arms battles. Also included in the box set is a BattleTech universe book providing an overview of the game world, its history, and its factions. A set of 24 unpainted plastic 'Mechs, ready for play and suitable for painting, are accompanied by prefilled record sheets listing each 'Mech's capabilities. The set also includes maps, a painting and tactics guide, cardstock reference sheets, a universe poster map of the BattleTech universe, and two six-sided dice. The 2011 "Twenty-Fifth Anniversary Edition" of this set replaced the 2007 edition's thin paper maps with board game-style mounted maps, added two additional "high-quality" plastic minis (a Thor and a Loki, with accompanying record sheets), and included a brief guide detailing the BattleTech gaming system intended to introduce new players to the various products for the game.
