Want a copy of the UnderWorld CD?
Back in 2000, I produced an RPG called UnderWorld (which is now available again, in PDF).
The only support release that ever came out for it was a CD of original electronic music, mixed with a “radio-show”-style story. Well, the composer is selling a few copies of the CD via eBay: so, if you never got a chance to grab one, do so. I think you’ll like it.
