Game makers Aspyr have re-released Doom 3, now in a version designed for modern Intel Macs. The game, first released on OS X in 2004, sports a rare (for the Mac platform) "M" rating for its nightmarish setting, violence and gore. The new version runs only on Intel Core2Duo or later chips under Snow Leopard or Lion, and does not work with the pre-Intel 3000HD integrated graphics chipsets. The engine for Doom 3 was released under the GPL last month.
