A Time of War is the fifth core rulebook in the line and is designed to mesh as completely as possible with the core rules for the BattleTech war game as described in Total Warfare and the rest of the core game series (including TechManual, Tactical Operations, Strategic Operations and even Interstellar Operations that will publish next year). The rules in A Time of War may thus be applied to the Total Warfare tabletop game with minimal disruption to the game play experience of either system.
