ChaosUT2 brings an entirely new feel to the game of UT2003, but does so without removing anything from the original game. Each and every weapon, item, and feature included, covering everything from optional Chaos startup menus, to custom quit messages, has been designed and tested to work with the latest version of UT2003.
Patch the for PR200 to upgrade it to version 201 and then you have the very last version.
