Subtitled as the Unofficial Guide for running Traveller® in the HERO System, TravellerHERO is a fan-created pdf for HERO System 5th Edition. It faithfully recreates all the essential Traveller elements (races, weapons, ships, gadgets, psionics, etc.) in Hero System terms. There are even sample starships, planets, and characters. This title allowed Star Hero players to experience, and play in, the Traveller setting.
This title appears to anticipate the two licensed books produced by Comstar games that combine Traveller & 5th Edition Hero ...(Traveller Hero Book 1: Adventurers in Charted Space & Traveller Hero Book 2: Adventure In Charted Space). These two titles appear to be an elaboration on the work done in the free pdf by the same team of authors.
