From the rules: Grind is a combat sport game for two players. Played in a gigantic, hazard filled stadium, two opposing teams of war jacks attempt to push a massive metal encrusted Grinder into their opponent's Goal Pit. The first team to score a goal wins the match.
Grind was originally published as a variant of Warmachine whose rules were released in No Quarter Magazine #10. It was later developed into a standalone board game. The rules of the new Grind board game have little in common with the original Grind rules for Warmachine miniatures.
