Larfleeze, the devious leader of the Orange Lanterns, has broken out his Santa hat for a little holiday mischief by hiding stolen presents around Gotham City and Metropolis. Heroes and villains alike can take to the streets to help recover the stolen presents to earn a few holiday-themed gifts of their own. Additionally, the update also includes a new PvP arena, a number of fixes and more.
Patch notes for Game Update 7 are available on the DC Universe Online forums.
