The Revolver (specifically a double-action .44 Magnum) is a secondary weapon available in Carnivores: Dinosaur Hunter HD and Carnivores: Dinosaur Hunter Reborn. It is a very loud weapon, and will scare away herbivores or attract hungry carnivores. It has an exceptionally fast rate of fire, and can fire off 6 shots before having to reload. It is also very lightweight and mobile, making it a nice personal defense weapon. The Revolver is the last peice of equipment available to buy, and costs 200 gems to use.
A similar revolver also makes an appearance in Carnivores: Dinosaur Hunter. Unlike the revolver from the HD version, this revolver has a five shot capacity, with a total ammo count of ten and a fairly staggering cost of 500 credits. The revolver can dish out considerable damage (rivaling the X-bow) at short to medium range, though its accuracy suffers at greater ranges. Its damage, coupled with a fairly admirable fire rate, makes the revolver excellent at eliminating charging predators, similar to its HD counterpart. Interestingly, the revolver is the only weapon in Carnivores: Dinosaur Hunter to have muzzle flash, and one of only two weapons (the other being the DB shotgun) that reloads before its total ammo supply is completely expended.
On september 2016 the revolver was added to the mobile CDH
