This is a port of id software's Quake World for AmigaOS 3.x, AmigaOS 4.x, MorphOS, WarpOS and PowerUp. QuakeWorld is a multi-player specific version of Quake, optimized for playing over the internet. It allows a server to predict the movement of an object based on its current speed and trajectory, so the server doesn't need to receive continuous data from the client and can deal much better with lags.
