Swarm Attack

Swarm Attack is a weekly mission given by Loyalist Galen in Mera's Royal Hideout in the bottom level of the southern edge of Atlantis (Location). It is only available after you have completed Atlantis (Mission) up till the point Aqualad asks you to queue for Atlantis: The Silent School.

Like previous episode weekly bounty missions (e.g. The Day the Island Stood Still), players are notified by a pop up red message when the boss is available to fight. However, it is not marked by a skull icon and the mission does not name the boss - Trench Mother, along with Trench Creatures and Adolescent Trench Creatures.
