The expansion features a "Risk-based strategic layer", a campaign including a "meta-map", similar to that in
Westwood Studios's
Dune games as opposed to the programmed, linear storylines of previous versions. Due to this lack of linearity, there is no plot aside from the opening cinematic; rather, as the player conquers various opposing factions the game provides a narrative specific to whom the player has conquered. If the player wins the campaign, a cinematic is played that depends on which faction the player was controlling.
The player may pick a faction to play as, and then engages in turn-based combat with the other A.I.-controlled factions. There are multiple provinces, which are conquered by fighting a regular skirmish match over them. These may either give a special bonus or supply special 'honour guard' units, which are powerful, non-trainable versions of regular units. They may only be made on the main battlefield overview screen, and, like provincial reinforcements, cost planetary requisition, a resource gained on a per-turn basis based on how many provinces the player controls. Honour guard units transfer over provinces and may be used repeatedly. There are also seven 'Stronghold' provinces that function as bases for respective factions; these are made like more traditional campaign games, with multiple secondary and primary objectives that vary from faction to faction.
