I'm happy to announce that the fourth beta of the UT3 Style Mutators for UT2004 backporting mod (codename PowerWheel) has been officially released today. Among the major changes in this release are reworked weapon materials, pickup meshes and pickup bases, weapon networking support, vehicle meshes as well as the addition of Hoverboards and experimental Necris vehicles.

You can find more information as well as download links in the main entry of the mod here.
