Britton Publishers released its squad-level WWII ruleset in 2004. Since then, it has undergone several revisions that help to make it the ultimate Close Quarters Battle (CQB) simulation for roleplaying and miniatures. The rules use a chit-based activation system that realistically reflects unit cohesion under combat conditions. The rules permit the player to generate a character with unique attributes for campaign-style games, or opt for a simplified approach that uses generic abilities. This scalable level of detail sets Final Combat apart from the competition.
