You won't find a more refined, more stable, or more fun Ultima Online server anywhere.

ABC was the first free server to add these features and will continue to be the first to add future expansions - but unlike other servers we won't annoy you with endless self-promotion. We feature the latest expansion content including the Stygian Abyss, the new loot systems, and both the classic and enhanced clients. Playing on ABC is free of charge we are completely supported by player donations. Whether you've been playing Ultima Online for years or are completely new to UO, you're sure to find ABCUO a fun place to play. ABCUO is the original no-skillcap Ultima Online server.
