Place them on your vehicle and create a loadout that fits the fight: • Weapons — guns, shotguns, shuriken cannons, lasers, homing bazookas, void beams, and tesla coils. • Armor — extra durability so you can take a hit and keep firing. • Gold Mines — extra gold after every stage to grow faster. • Boosts — more damage or a higher fire rate for every weapon on the machine.
