Campaign Operations contains rules for creating and running forces, whether a down-on-their-luck mercenary battalion, or a fully-supplied House regiment. The volume also contains complete rules for devising solar systems, allowing players to recreate existing star systems or craft all-new worlds to challenge each other. The final sections of the book bring several options to the table for campaign play. Building off of previous sections in Total Warfare and Strategic Operations, the Narrative Campaign, Map-Based Campaign, and Chaos Campaign rules allow players to build exciting, fun campaigns of almost any stripe for their newly-minted forces!
