Iris2 update
Despite suffering a server error and site crash over the summer, the team at Iris2 (also known as Ultima: Iris) have kept up development on their 3D client for Ultima Online freeshards, and have just released build 3154 to the general public!
You can find downloads at the project website, or at the project entry here at Aiera. Note that I have only restored the downloads for Iris2; downloads of the original Iris (before the transition to OGRE) have not yet been restored.
