Operation Pill

Operation Pill is a game about a small pill that enters your body to fight disease-causing bacteria. You control a capsule flying through a blood vessel and destroy pathogenic bacteria with a germicidal gun, while using an electrostatic shield for defense.

Fight through the vessel

Red barrels destroy everything in their path. Inaccurate shots can kill neutral cells and weaken the organism, so you need to avoid hitting them. You can collect weapons, additional shields and lives.
