Epic Games has released a new version of the PS3 Mod Tools for Unreal Tournament 3, a toolkit for mod authors. If you want to take advantage of these tools, you should have Unreal Tournament 3 for PC, patched to the latest version, installed on your local machine to get started. To access the sound conversion tools, simply click through the ATRAC end-user license agreement (EULA) here, install ATRAC on top of UT3's PS3ModTools v2.1 (which enable the cooking of PC mods for use on the PS3), and begin importing files.
