In a future city, the crime is so bad that the police are unable to control it. A monster named Smash Monster has just been released from prison, and he is going to destroy the city in order to prove that he is not guilty. The police have to do something quickly to stop him, because he is going to destroy the whole city.

In order to stop him, the police have to use their special weapons, which they have developed in the last few years. The weapons are all machine guns, shotguns, and grenades.

They have to fight him, because he is very strong and they will not be able to capture him unless they kill him.
