In this exciting shooting game, you play a soldier dressed in yellow and armed with a powerful submachine gun. Your mission is to defeat a series of mad scientists who have begun to invade the city, wreaking chaos in their wake. As you progress in your task of protecting the city, you will encounter an increasing variety of enemies, including not only scientists, but also small and large robots that present unique and dangerous challenges.

Every time you manage to defeat all the enemies in an area, you will be transported to a special store. In this store, you will have the opportunity to spend the coins you have earned during battles. You can upgrade your weapon, making it more powerful and efficient, or purchase additional skills. These skills include the ability to strategically place grenades or set up traps to stop enemies from advancing. With each upgrade and skill acquired, you will become stronger and better prepared to face the intensifying threats that lurk in your quest to save the city.
