It has been accidentally leaked (via an email that wasn't supposed to be sent yet) that City of Heroes will be receiving its second official expansion pack, titled "Going Rogue."

From the email:

"Paragon Studios™ is proud to officially announce the next City of Heroes® expansion, City of Heroes Going Rogue™! This will be the first major expansion for the City of Heroes franchise since the launch of City of Villains® in 2005.

Praetoria, a utopian mirror to our own world, hides a dark secret. Exploring this mysterious alternate earth, the heroes and villains of this world feel an uneasiness of doubt creep over them. Loyalties are questioned. Choices are made. Lines are drawn. As they search for the truth behind Emperor Cole and his Praetorian guard, brutal foes and fierce allies emerge, turning this once blissful paradise into a battle ground.

City of Heroes Going Rogue officially opens the "mirror universe" of Praetoria and an all-new alignment system that explores the shades of gray that lie between Heroes and Villains. For the first time, Hero characters can become Villains and vice versa, enabling Heroes to cross over to the Rogue Islesâ„¢ and Villains to experience Paragon Cityâ„¢.

For more information, read the official press release and check out our new Going Rogue website to view the announcement trailer and register for the latest news and updates for City of Heroes Going Rogue."
