New content available to returning players through the Return to Britannia Campaign includes Mondain's Legacy, the 7thUO expansion which introduced the playable Elven race and dangerous, new dungeons to explore. Mondain's Legacy was made available at no charge in August 2009 to existing subscribers and to new players as part of the Ultima Online 14-day free trial.

"We're hoping that, as part of the Return to Britannia Campaign, former players will once again rediscover the joys of Ultima Online," said Jeff Hickman, Executive Producer for Mythic Entertainment. "UO was the first love of many MMORPG players, and it still holds a special place in their hearts after 12 glorious years. I think returning players will be pleasantly surprised to find a thriving and vibrant community from around the world ready to welcome back their former compatriots and include them in their ongoing adventures."

Players returning to Ultima Online through the Return to Britannia Campaign can download and install the UO client for free. Players who no longer have access to their Ultima Online username and password can retrieve their account information.

Ultima Online: Stygian Abyss, the 8th expansion was released earlier this month and revolves around the introduction of the playable Gargoyle race. Players will also find expansive new areas to explore, including Ter Mur, the Gargoyle homeland, and the Stygian Abyss - the largest dungeon area ever introduced to Ultima Online. This sprawling dungeon contains new boss monsters of unparalleled difficulty, including the Medusa, Primeval Lich and the Stygian Dragon, as well as Player vs. Player zones where adventurers are turned against one another.

Ultima Online: Stygian Abyss is now available at UOGamesCodes.com and the EA STORE for $29.99.
