Upgrades for Heli Hell - iPhone iPod

• Upgrades

Use the ship to upgrade your weapons. You can upgrade both missiles and guns up to three times with each vehicle you obtain. Upgrade your guns first, as a faster firing rate is helpful. If you have the money, spend some into missiles for secondary firepower. Then, use your weapons upgrades to make saving coins easier for better helicopters. Newer helicopters have better firepower and can last longer due to their improved armor.
