Whatever Admonition's been up to seems to be infecting the population. Horde sightings are on the rise, with some districts entirely lost to the shambling horrors. This isn't a case of a single hab-block falling. This is something much darker and could be the herald of worse to come...
The streets are choked with hordes of infected enemies! To make progress in the event, complete missions with the Endless Hordes modifier.
The event is LIVE NOW until September 2! The rewards will be Ordo dockets, Plasteel and Diamantine. Those who complete the last tier of the event will receive a cosmetic insignia.
