The Great Devourer is the first deluxe expansion for Warhammer 40,000: Conquest, and it introduces a brand-new faction to the game: the Tyranids! Two Tyranids warlords lead these horrific creatures into battle, each offering a very different play style. In addition to these warlords and their signature squads, you’ll find a host of new units, supports, events, and attachments to support the Tyranids, including an entirely new type of unit, the synapse unit. The Tyranids aren’t the only ones to benefit from this expansion, however. Every other faction must make its stand against the Great Devourer in the Traxis sector, and brand-new unique characters help them to battle the Tyranid threat.
