Classic Ultima Online

Welcome to the Classic Ultima Online (CUO) project page. CUO is a game engine under development that will allow users to create and publish classic Ultima-style online games.

The demo project packaged as part of the CUO download will be an online recreation of Ultima IV: The Quest of the Avatar, perhaps the most popular Ultima of all.

Preview Ultima IV Online

Navigate to the alpha shard hosted by Dennis De Marco at http://www.demarco.com/ultima. Download and launch the client, specify u4m.demarco.com as the game server, and then create a player.
