Like the yawning chasm into Hell itself sits the entrance into the foreboding dark caverns of the Stygian Abyss. Now existing Ultima Online players can upgrade their accounts to get Stygian Abyss, the eighth incredible expansion pack for the best-selling massively multiplayer online roleplaying game, Ultima Online. This is the largest, most detailed, and deadliest dungeon ever created for Ultima Online. Inside, find a long-lost temple, the entrance to the world of Ter Mur, homeworld of the Gargoyles. Masters of both combat and magic, Gargoyles are now a playable race in Ultima Online.
The Gargoyle race presents fascinating new powers, including the ability to fly and reach areas other players cannot; the capacity to call upon their natural ferocity to go berserk in desperate situations; the ability to hurl objects with great accuracy; and a unique mystic insight that grants them basic magic spell usage. The sudden appearance of a new volcano beckons players to the Stygian Abyss, and the evil that lies within. Gather your group, gather your weapons, and gather your wits… it’s time to descend into the Stygian Abyss.
