Slugs and Rockets mod for Quake III Arena, ioquake3 and the quake3e engine.
SlugRock, short for Slugs and Rockets, is a Quake III Arena mod based on the ioq3/quake3e engine.
The mod allows the player to set up different gametypes with the railgun and/or rocketlauncher.
Have you always wanted to play TDM where the blue team plays with the rocketlauncher and the red team with the railgun? Or a FFA game where you have the railgun and all the bots have rocketlaunchers? These are just two examples of the many ways you can set up a match with SlugRock.
Reommended is the quake3e engine, an improved version of ioQuake3.
