From publisher blurb: Sentinels of Echo City starts with a simple premise: WHAT IF? What if the makers of the FASERIP game engine decided instead to use the B/X rules as their inspiration? What if this game came out in 1984? In this game, you join with other like-minded super heroes, working together to fight crime, uphold justice, and save the world from the various forces that are always trying to take it over. This book contains the core rules needed for ongoing play.
