The Hypno Knife can turn an enemy Cryptid (with the exception of Lepers, Seekers, the Breeder, the Kraken, the Mammoth, Gargoyles, Bombers and Ancestors) into an ally. Rhinos can be turned friendly, but only through an upgrade in the armory that costs 50 teeth. These converted Cryptids are still attracted to Flares, so it is not advised to deploy one until the Cryptid is dead.
There can be multiple converted Cryptids fighting for the player at once, but this is dependent on the amount of knives that have been found.
When a Cryptid is taken over, money is rewarded based on the type of Cryptid it is. They are highlighted blue and will have a blue shield icon above them. They will also have a grey smoke effect, much like some of the campaign's cutscenes which include the Ghosts inside of vehicles.
