“Teleios Ascendant is a new level 40 Epic Villain Lair containing some of Teleios’ newest cloning creations. This lair is the biggest challenge in Champions Online to date, with lots of new rewards for your heroes!
In the wake of Supervillain Onslaught and the resulting rampage of super-powered clones, UNTIL has activated “Project Frankenstein”. This new UNTIL Special Project under the command of Major Paul Mason keeps watch on the activities of the mad cloning genius, Teleios. Recently, UNTIL agents have discovered Teleios was nearing completion of his “Ascendency Formula”, enabling him to become Master of Humanity. UNTIL has authorized a UNITY strike force comprised of the strongest heroes to take him down!”
Patch notes — quite a lot of them — have been published to the official forums.
