Intro

Intro is the introduction to the main Prodeus campaign. It is the only level that can not be revisited and the only level that doesn't check for score. Killing all of the enemies is considered impossible since most are inaccessible. It marks the introduction of the Fiends Pro, the Fists, and the Pistol. It also foreshadows the Slayer, the Hunter, and the Plexus. It is followed immediately by Sacrum.
