Beyond the gates of the Maw, savage enemies raise arms against the Imperium. Rogue Traders, backed by the might of the Imperial Navy, must arm their vessels to wrest fortunes from their enemies in bloody warfare!

With Battlefleet Koronus, a Rogue Trader supplement, new rules and components allow Explorers to man some of the Expanse's most powerful warships! Take the helm of grand cruisers and battlecruisers and decimate your foes with torpedo salvoes, attack craft wings, and fearsome Nova Cannons. Learn of the Imperial Navy and its squadrons in the Koronus Expanse, the famed Battlefleet Koronus; their ships can prove useful allies, or powerful enemies. Then study the dread warships of vile xenos races and villainous Chaos reavers, the better to know and destroy your foes!

Rules for NPC starships and squadron operations make space combat easier to run than ever before; plus, rules for waging ground wars allow you to fight entire campaigns to the final blows!
