A new patch will give you some cool enhancements for your City of Heroes account.
The "flashback" ability will allow you to go back in time and "participate in exciting events from the history of Paragon City and the Rogue Isles. Heroes and villains can also use this feature to play or replay hundreds of missions from earlier in the game," according to Matt Miller, lead developer for both City of Heroes and City of Villains.
In addition to flashback, there is also a new weapon customization tool. All of this in a free update!
