Rat Musou is a top-down action survival game where you play as a lone exterminator armed with a chemical backpack sprayer. Endless waves of rats swarm from all directions — dodge, spray, and unleash powerful skills to hold your ground.

Battle through five themed arenas: grimy sewers, chaotic night markets, a bustling food court, a neon cyberpunk district, and a frenzied Japanese summer festival. Each arena brings new rat types and escalating danger.

Key Features:

• Diverse rat enemy types, each with distinct behaviors

• Powerful BOSS rats with increasing difficulty
