This isn't one of my own products; it's from FeralGames. I haven't read it myself yet, so take it for what it's worth, but the premise is very cool. It's on a very deep sale today -- Memorial Day only -- on Tabletop Library.
It's a $7.99 product selling for $2.99.
Premise: You are dead and have awoken in Limbo, in order to reach the hall of Heroes you must climb the Mountain and gather souls.
