The Mano a Mano Role-Playing System (RPS) is a set of generic role-playing game rules with emphasis on hand to hand combat. (In Spanish, "mano a mano" means "hand to hand".) The Squawk Role-Playing Game (RPG) uses the Mano a Mano rules for combat, abilities, character creation, and so on.

The Mano a Mano RPS is free and "Open Source", meaning that anyone may download the Mano a Mano rules, modify them, and even use Mano a Mano to create their own Role-Playing Games. (The Squawk RPG is not Open Source.)
