"War Is Hex is a supplement for any TTRPG using a hex or gridded map to represent an ongoing war of two or more factions. It gives a table the ability to play in a living world where front lines move, forces dig in, and battles change the terrain, quickly and without pages of crunch. WIH is intended to make adventures more meaningful by allowing the players to have a direct influence on the course of a war and for that war to have an impact on the players’ future adventures."
