Animalball Melee

A stand-alone gladiator combat game using a simplified d20 ruleset. Players create fighters and resolve fast, one-on-one battles with streamlined movement, attacks, and damage rules. Designed for two to six players, it supports quick pick-up-and-play matches and can also serve as the combat system for a broader roleplaying campaign. Open Game elements remain, while nonessential rules are removed to focus on physical combat.
