Marshal your forces and prepare to conquer the Inner Sphere! Interstellar Operations: BattleForce provides a sliding zoom that can scale from a quick game on your table up to the macro level, allowing players to assume the roles of House Lords and dominate the galaxy! BattleForce is a complete, all-in-one-book game system of combat on a grand scale, but tailored to your interest at the gaming table. Play lightning-fast, large-scale games like battalion vs battalion or conquer a planet with multiple regiments. Not large enough? Invade an entire sector of a House as armies clash across a dozen systems. Still not large enough? Become a Clan Khan or House Leader and amass all the industrial might of your empire to protect your worlds and defeat your enemies! Note: The original publication of Interstellar Operations had rules for playing in alternate eras which can now be found in the Interstellar Operations: Alternate Eras.
