NCsoft has released a trailer from A Stitch in Time, showcasing the eleventh free expansion to the City of Heroes universe. In this issue, the mysterious Ouroboros organization, a group of beings from the ends of time, enlists the aid of Heroes and Villains to rewrite the past. Heroes and Villains are able to travel through time using the new Ouroboros System, which opens the gates to both new and existing content for players. Issue 11 also unleashes two brand new power sets: Dual Blades and Willpower, giving Heroes and Villains a slew of new power options.
