2 maps. Both are pretty nice-Double Helix takes a bit of getting used to. (Seems like it's got a 5-D aspect to it, but it doesn't...) This is one of the few attractive Pfhor levels. Lysurgic Dilithimide requires quick footwork to stay out of the lava...
A pretty simple maze, with a somewhat hard-to-find center room. (Much easier if you're not playing this networked... more time.) Nasty Minotaur... but he's not too bad to kill, the first time.
