Virus hunter

Command a tiny submarine on a microscopic battlefield, hunting dangerous bacteria, viruses, and cancer cells deep within the body. Navigate narrow passages, scan for threats, and strike with precision. Upgrade your submarine by buying stronger hull protection, faster engines, advanced torpedoes, deep mines, and specialized weapons. Earn achievements by clearing zones and defeating powerful enemies—each achievement unlocks permanent improvements to your submarine. Dive deeper, fight smarter, and evolve into the ultimate microscopic hunter.
