Trials of Atlantis will introduce the ability for players to swim, discover and explore the submerged civilization. The expansion reveals that the citizens of Atlantis, foreseeing the demise of their society, built a series of Trials into the ruins of their civilization. The Trials were designed to challenge future cultures that discover and seek to explore the ancient lands. In Trials of Atlantis, the three Realms have each found a hidden portal to the fabled continent. Now it’s up to the populations of Hibernia, Midgard and Albion to take on the nine Trials and uncover the mysterious powers amongst the ruins. To suceed, players must master the perilous ocean and confront terrifying monsters, both on land and undersea.

Trials of Atlantis is designed to further challenge high-level players by introducing a Master Level advancement system. As a player moves sequentially through each of the nine Trials, they will achieve a corresponding Master Level. Emphasising group play, the Trials will have to be surmounted by groups of players journeying through the portal together. Players will be able to travel by boat, explore islands with ruins, swim to submerged dungeons and battle new creatures in underwater caves. Additionally, the expansion will add one new player race per Realm, dozens of new monsters to encounter, as well as new objects and treasures to uncover.
