For the Ice Age sequel, the storyline is an addition to the original storyline. DinoHunt Corp. scientists discover Ice Age animals living in the Arctic regions of planet FMM UV-32 and they set up a separate hunting program for big game living there. It also features better gameplay and a new supply drop feature, which can be used once per hunt and refreshes the player's supplies. One more addition is the existence of a "secret animal" that can be unlocked by obtaining 1,000 points.
As featured in the Wizard Works Outdoors Complete Software Collection, Carnivores Ice Age featured a slightly altered title design. The blood-styled lettering of "Carnivores", instead of red, is the same light blue color of the "ice age" displayed underneath. The title also featured a "3" designed like the "2" of Carnivores 2, although the "3" is a light blue color.
Other than the different animals, locations, equipment, and the new "Supply Drop" feature, this game is basically the same as Carnivores 2, featuring virtually identical graphics and similar AI.
All of the animals in Carnivores Ice Age are capable of killing the Hunter.
