A "Battle System" refers to the mechanics and rules that govern combat in video games, tabletop games, or role-playing games. It determines how characters or units engage in conflict, including actions like attacking, defending, and using special abilities. The system can vary widely, from turn-based strategies to real-time action, influencing gameplay and player experience. Different types of battle systems may include elements such as hit points, damage calculations, and status effects. Some systems allow for cooperative play, where players work together against enemies, while others may feature competitive elements, pitting players against each other in player-versus-player scenarios.
