Each of the 32 levels in the Full Edition of PERDITION'S GATE makes for an extremely difficult experience in single player mode, with innovative level architecture further defining the "classic" feel. Monsters, health, armor, and ammo have all been skillfully arranged to ensure that PERDITION'S GATE is difficult, but not impossible, for players of all skill levels. Levels are also riddled with secret areas and items; you'll want to play then again and again trying to find every last secret. (taken from PERDGATE.TXT)
