A Sub-Trope of Awesome Backpack, the Ammunition Backpack is there if you use More Dakka, but don't have Bottomless Magazines, or just don't have enough space to carry more ammo in your pockets or Badass Bandolier. Common for characters using hand-held miniguns (such as Blaine in Predator and the T-800 in Terminator 2) or other portable machine guns. Also included are fuel tanks for flamethrowers, portable power plants for science fiction guns, and the like, and quivers for The Archer. In Video Games, you can bet that damaging the tanks will defeat enemies For Massive Damage.
