Ultima Online: Age of Shadows is the sixth edition (fifth expansion) of Ultima Online. This expansion adds a large new land mass, Malas, and a dungeon called Doom.
Malas provides significant space for building which is complemented by tools for placing and designing of customized houses. New features include the Necromancer and Paladin professions, attack moves, monsters, weapons, and a skill. Several improvements where made to the game's graphics as well. The game comes complete with the original game and all previous expansions, so no further purchases are necessary (but the monthly fee applies as always).
