Ndoors Interactive is set to launch their December update for Atlantica Online today.

Dubbed "Call of the Wild" the update adds a number of new features, including the first "A" class mercenary to the game: the Druid, a new Grand Canyon dungeon, a Squad system, which allows for groups of up to 30 players to link up and tackle content, such as the newly introduced Squad Dungeon, Coyote Valley, and finally, the Colosseum League, which allows for players to fight each other on fair terms.
