BattleTech is a turn-based, multiplayer game, typically played on a map divided into hexagonal grids with miniatures representing the various 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. The game system uses three-dimensional miniatures (the plastic miniatures found in the Classic Battletech Introductory Box Set, must have to play) or the complete line of Classic BattleTech metal miniatures sold by Iron Wind Metals
