For a limited time, Open Episodes are returning to DC Universe Online. Between now and the end of the year all players will be able to play the content in Episodes 1-26 with their friends — whether they’ve paid or not. (This means you don’t need to be a member or have bought the episode content to join in on the fun.)
Of course, there are limitations to this free-for-all. For instance. Episode 27: Amazon Fury Part III will not be included in the open content and will require a purchase to play. In addition, those who have not purchased the episodes in question will have longer loot lockout times than those who have. Finally, the content does require a combat rating of 43 and players must meet the minimum required by each episode in order to play them.
Full details on this event are available on the DCUO site.
