UOCataclysm is a perfect blend of the best of Sphere 51a, T2A and what many of us consider the 'golden age' of Ultima Online. UOC has spared no expense to design a server which functions with all of the greatness of the original Sphere but powered by RunUO. Be apart of a rich, custom world with a unique flair and quality the most nostalgic can appreciate. Finally a server you can enjoy that lives up to its promises on being true to the original Sphere playstyle!
