Quasar Water War transforms FiveM into a competitive water battle experience where administrators can create custom arenas directly in-game, players fight using water guns inside polygon-based battle zones, and the top performers earn configurable rewards. Designed for ESX, QBCore, QB, QBox, and Standalone-compatible frameworks with automatic detection, it features synchronized multiplayer battles, live scoreboards, custom arena creation, persistent SQL storage, and real-time arena management without server restarts.
