Welcome to UO Cataclysm


Marketplaces reminiscent of a lost era..

The Frost Elf Den, a dangerous destination for an adventurer.

Custom crafting includes weapons, armor, potions and more!

Lively towns centered on a bustling economy.

Rare custom mounts can be tamed only by the brave.

Perilous journeys into our dungeons await.

Static houses are available for your RP pleasure.

Custom Mob Locations with Storylines Around the World.

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!

Patch 32 Maintenance Patch deploys on Cataclysm!

We've made some strides on era accuracy! Paralyze Field now functions per Sphere 51a and cannot be abused. Stealth also is now voided in tournaments. You can no longer hide and heal at the same time.

Patch 31 is live! The Server has been moved!

Today we moved the server from Dallas, Texas to South Carolina. This will improves pings for all East Coast USA players and notably improving the connection for our European players. We also launched Patch 31, which is a Maintenance Patch containing mostly content needed for the next release. Hiding is no longer allowed in tournaments.
