This level is a huge disco club that is overrun by aliens. There are new enemies in this level, such as the Magnum P.I.G. and an assault trooper that appears to have a wig on with normal clothes that dances (see the picture below). The Magnum P.I.G.'s make their one and only appearance in this level. In addition the level also features non-hostile alien disco visitors along with DJs and hooded aliens. This is also the only level that features the music being heard differently. For instance, when you're outside of the dance area you hear the music a little closed, but when close you can hear the music better. The level culminates with the final boss battle against the CyberKeef.
Throughout the level are posters for a cancelled 'Notorious P.I.G.' concert.
In the Plug N' Pray mod, the Cyberkeef does not appear in this level, but was replaced by the Battlelord.
