I started working on a new Postal 2 project, Crypt Of The Damned. It's hopefully going to be a 3 map mini campaign in which the Postal Dude wakes up in a crypt and has to fight his way through a cult. I haven't really figured that much out though, so this is mostly just conjecture.
Here's a screen from the first map. I'll try and post progress about it from time to time.
