A convoluted map, with teleporters everywhere, lots o' baddies (or just some, depending on which version of the map you play), and the Gallerie de Despayre, where nasties fall on you unremittingly from out of the sky. Rain of Pfhorror, with the excess baddies, is great for solo practice, and Drizzle of Pfhorror holds an acceptable number for net play. Been sitting in my inbox for way too long now...
