The Revolver (specifically a double-action .44 Magnum) is a secondary weapon available in Carnivores: Dinosaur Hunter HD, Carnivores: Dinosaur Hunter Reborn, and as a primary weapon in Carnivores Dinosaur Hunter. 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 piece 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.
