Carnivores Wiki

Double ammo is an accessory in Carnivores 2 and Carnivores Ice Age which gives the hunter double ammunition for each selected weapon in each hunting session with no point deduction.

In Carnivores: Dinosaur Hunter or Carnivores: Ice Age (iOS), Double Ammo is not present as an accessory. It is however implemented by default as all weapons have double their ammo count.

In Carnivores: Dinosaur Hunter HD and Carnivores: Dinosaur Hunter Reborn, Double Ammo costs 125 gems to use, and deducts 10% of the total points acquired on a hunt.
