About UO Cataclysm

What is UOC?

We are proud to announce the UO Cataclysm Project, an Ultima Online Free to Play Shard powered by RunUO. Based on the widely missed, delightfully nostalgic, and down-and-dirty fun to play UO era that is the Sphere 51a Playstyle, Cataclysm at its core replicates the necessary game-play mechanics for this play-style and presents itself in a way familiar to those who are fans of the genre. Our world is full of creative, custom armors and unique and dangerous dungeons to explore. Much game play was taken from Sphere such as PVP, PVM, Felucca Only, No Pre-Casting. Sphere at the time was also incomplete, so we've added the finishing touches that we felt it would have had back then, should it have been as mature as RunUO is today. Cataclysm UO was widely inspired by many Sphere 51a servers from the 2001 – 2004 era, such as Imagine Nation. Many of the core game-play features of this genre are from The Second Age era of Ultima Online. Your familiar Ultima world has been transformed into a detailed colorful land full of friend and foe.
