User summary: Treasure Hunter is a sort of "tomb raider" adaptation of the Portable RPG System. The entire Portable RPG System is included in the document, as well as setting information and alternate rules to horseback riding, crypt exploration, and trailblazing. Several types of undead crypt denizens are details. The whip is given an entry in the weapons table. Characters in the system have four Attributes: Strength, Dexterity, Intelligence, and Charisma. Attributes have a numeric value ranging from 1-10, with 4-6 being typical. Players can either randomly generate Ability values using 1d10 or perform a point distribution from a pool of 24 points. Characters then select equipment.
