The Midnight Squad
Join the Midnight Squad (Levels 10-20)
The clandestine organization of mystics, scholars and mages, known only as the Midnight Squad, seeks to rebuild its numbers since the devastating assault of the Rikti Invasion. The Midnighters hold a secret that could bring the alien assault to an end, but without the help of the Heroes of Paragon City™ it will remain Lost forever.
New Roman-Style Zone Maps (Levels 35-50)
The Midnighters hold many secrets within their walls, including a highly coveted Ouroboros crystal, enabling them to travel to the far reaches of time. There is a familiar threat in an ancient land and the Midnighters need the help of both Heroes and Villains to stop it. Players step foot upon the ancient land of the Roman Cimeroran Peninsula, where they battle deadly creatures, defend an ancient city and ultimately come face to face with the enemy of time itself. Throughout this journey players uncover the mysteries of power and the origins that guide them today.
Unlock Roman-Style Armor Costumes
Through their accomplishments, players unlock the new Roman themed armor costume set.
Villain Epic Archetypes
Infiltrate the Arachnos organization from within! Upon reaching level 50, Villains unlock two new Epic Archetypes; Arachnos Soldier and Arachnos Widow. They have their own unique storyline and missions, power combinations and costume sets. Branching powersets allow the Arachnos Soldier to specialize as either a Bane Spider or Crab Spider and the Arachnos Widow chooses from the Fortunata and Night Widow branches. Each brings with it unique costumes for your Arachnos duties, as well as your newfound role as a Destined One.
Using his newly built Resonance Manipulator, the Villain scientist known as Dr. Brainstorm™ has discovered a way to alter the energy strands which connect every Hero and Villain to their powers. This discovery has not only opened the door to new powers for his fellow Villains in the Rogue Isles™, but has also done the same for the Heroes of Paragon City ™! Specifically, new characters of almost every Hero and Villain archetype gain access to an additional primary and secondary powerset that they didn’t have access to previously. Details to come!
