The world has been taken over by the mutants. It has been over ten years but were still fighting for the city.
As a surviving soldier your goal is to save humanity by using firepower!

-Upgrade your shooting speed by going through green gates or breaking one of the gun crystals.

-Purchase a supply crate to unlock new weapons of different rarity levels. The supply crates may also give keys to unlock your own personal mutants.

-Control your research group of mutants in your own training ground. Your mutants will help you learn more about the enemy and produce upgrade materials.

Can you defeat the horde of mutants and take back the city?
