Cover scent is an accessory in Carnivores, Carnivores 2, Carnivores Ice Age, Carnivores: Dinosaur Hunter, Carnivores: Ice Age, and Primal Prey which masks the hunter's scent, making detection through scent less likely. In the Carnivores series, using cover scent on a hunt deducts 20% from the total points acquired during that hunt.
In Carnivores: Dinosaur Hunter HD and Carnivores: Dinosaur Hunter Reborn, cover scent costs 75 gems to use, and will deduct 5% of the total points acquired on the hunt.
Cost: $2,500- Cover scent will help to reduce your "human" scent, allowing you to go a little more undetected by both prey and predator dinosaur species.
This cover scent comes in a spray bottle, but doesn't actually change how undetected the hunter can pass by dinosaurs.
