I finally got around to finishing apsp3; A map I started way back in late 2005 for the chapters map pack for Quoth. Since it missed the deadline for that pack by 5 or 6 years, it turned into apsp3, languishing on my hard drive for months at a time, before I eventually finished it off.
It's a very large SP map with lots of secrets and plenty of monsters. It requires Quoth (yup, even if you're Daz), an enhanced engine like Fitz or Quakespasm, and yes, it does use the Quoth monsters ;-)
