In Suicide Mission, you take control of a microscopic submarine navigating the bloodstream of a person infected with a virus. Your objective is to eliminate the virus and save the patient. Each time you shoot a cell infected with the virus, it splits into smaller fragments. These pieces will continue to divide until they are small enough to be completely destroyed. Once all virus particles have been eradicated, you can proceed to the next, more challenging level.
The game offers three levels of difficulty, allowing players to customize their experience based on their skill level. Additionally, players can choose between two shooting styles for their submarine: single torpedoes or rapid-fire mode. This engaging gameplay concept puts you in the role of a microscopic defender, fighting off the deadly virus and restoring health to the infected individual.
