Version 2.5 of the Q1Q3 Pak is now available, providing a way to add a bit of a "Quake1 flavor" to Quake III Arena, though it's become a bit of a multi-flavor add-on, as in addition to providing some Quake sound and vision, it also makes the railgun behave more like the Quake II rail, and offers the chance to play as the Doom Marine, as well as the Quake Ranger.
