UO:98 is an extension to the UO Demo released by Origin Systems in 1998 on the Ultima Online:Second Age CD. The UO Demo (demo) is an offline tutorial for Ultima Online. The Demo featured only the town of Ocllo, and a quest that a player could complete while learning about the Game and Client. UO:98 unlocks many of the features that exist in the UO Demo such as the ability for others to connect with a regular UO Client, the ability to use the built in staff tools, and the expansion of the playing world to the entire map, and world saving. UO:98 also adds new features such as an accounting system, full world decoration, and support for later UO Client versions.
The UO:98 distribution requires (at a minimum), the following software installed or available on the target platform.
- Microsoft Windows XP, Vista or 7
- Microsoft .Net 4.0 Client Profile.
- Ultima Online Client version 1.25.35 through 5.x
