Customization Options
Although the weapon can't be customized per say, it can select two different modes of operation.

Normal mode: The gun can shoot a singular bullet or more depending how long you hold the trigger. Although it has a lower rate of fire, it's more accurate then in rapid fire mode.

Rapid fire: Upon activating, the barrels will spin, creating a Gatling-type 'barrel'. It has a higher rate of fire, but it's less accurate and prone to overheating, which can cause the gun to malfunction, shooting bullets all over the place until it cools down
