As promised, Epic has released the Unreal Tournament Bonus Pack for download at Gamecenter. It comes in PC and Mac versions as a 13.8 MB download (that are actually the same file though, so no need to get them both), and contains 11 new multiplayer levels, 3 new character meshes, and the Relics, special items that imbue a player with certain powers. Update: Epic has posted the Bonus Pack README page on the official Unreal Tournament site.
