The Daemons of Khorne have arrived 

The latest playable faction in Warhammer 40,000: Battlesector is the warp-fueled expressions of fury and violence. There are eight terrible units ready to bring Chaos to the cosmos, including the fearsome Daemon Prince. Bring your Blood Legion troops to bear in skirmish and multiplayer conflicts, as well as in a Planetary Supremacy campaign.

Bloodletters and Bloodcrushers are ready to charge into battle, propelled by wrath and an insatiable desire for slaughter, while the Flesh Hounds seek those who have dared to insult the Blood God without mercy. The Bloodmaster leads these horrors into battle: powerful Daemons that employ evil rituals to tear a hole in the fabric of reality, allowing more of their kind to flood forth and sacrifice blood for their ever-thirsty god.
