Based on the original game by Bethesda Softworks and iD Software, Aspyr has ported the first-person shooter Rage to the Mac in a "Campaign Edition" that features bonus equipment and missions formerly exclusive to the Rage: Anarchy Edition for the PC and Xbox. The Mad Max-style post-apocalypse adventure uses the iD Tech 5 OpenGL engine and represents the first entry in the Rage franchise for the Mac.
