My only good map pack.
So Underworld isn't totally dead yet. I do make levels occasionally, and I've added two to this version: Parc and The Multiplex.
Parc was formerly known as Pillow, and has seen a few small-but-helpful improvements since its original appearance on Pfhorums. The Multiplex was my contest map for Ryoko's 2008 Summer mapmaking contest; it didn't even get into the Victory Dance VI pack, so I thought I'd release it here for posterity.
A very fun netpack to play, with a variety of great different sized netmaps for different amounts of players. It has some nice 7-poly maps too! I definitely recommend downloading this pack!
