Weapons play a key role in winning the game. All vehicles come with a pair of mounted machine guns. They are weak in power, but have unlimited ammunition. Additional weapons scattered throughout the environments can be picked up and utilized if the player drives through them. These weapons include a variety of missiles, bombs, napalm and mortars. Each vehicle can execute three categories of attacks: "Special Weapon Attacks", "Advanced Attacks" and "Combo Attacks". Special Weapon Attacks are unique to each vehicle and are unlimited in stock, but need time to recharge if used repeatedly. Advanced Attacks allow the player to attack enemies when the player is out of weapons, but they can only be used if the Advanced Attack Energy Bar on the lower-right corner of the screen is fully charged. Most Advanced Attacks require three or four buttons sequences to initiate. Combo Attacks combine Advanced Attacks and maneuvers with weapon pick-ups. Combo Attacks can also be performed with a vehicle's special weapon. Due to the open-environment nature of "Twisted Metal III", there are numerous possible combos and strategies to invent and discover.
