Test the Ultramarines in a new event.

"Did the machine in your skull refashion your loyalty into madness?"
– Roboute Guilliman

Play as the new Ultramarines in the new event! During the Great Crusade, an Ultramarine and World Eaters joint compliance turned into a bloodbath at Angron's discretion. Tensions rose when the Ultramarines saw the acts of their brother legion.

Fight in the new 'The Cleansing of Ariggata' event and decide which cosmetic will become collectable. Do not miss this chance to test the new content in battle and start your Ultramarines collection. Every reward crate in the event has a chance to yield one of the new cards!
