Iron Gauntlets is a modular, adaptible ruleset for Fantasy RPGing. It utilizes the Impresa system (d10), but also can be used with the genreDiversion (d6) and Active Exploits (diceless) systems, and also provides guidelines for OGL conversion. Both a full bestiary and magic section are included in the book.

Iron Gauntlets Expanded is system-generic, but includes the default setting of Amherth. The overall flexibility and customization potential of the system helps enable it to be utilized by both veteran and novice gamers alike.
