Matt Miller, senior lead designer behind the City of Heroes, has posted a new developer diary on NCsoft's acquisition of the franchise and also discusses the upcoming Issue 12 add-on.

"...For the immediate future, however, I am pleased to announce “Issue 12: Midnight Hour” for City of Heroes, which will be going into closed beta testing soon. “Midnight Hour” brings with it a slew of exciting new features including the long anticipated Villain Epic Archetypes, which will be available to anyone who achieves level 50 in City of Villains. The current Hero and Villain Archetypes will benefit from Powerset Proliferation, where we took over twenty existing powersets and gave them to Archetypes that didn’t have access to them before. If you ever wanted to play a Controller with the powerset of Plant Control, now is your chance! Psychic Blasters are now a reality, as well as Axe and Mace wielding Brutes. With Powerset Proliferation players now have even more character combinations to choose from."
