Perhaps Ubisoft missed a trick by not sneaking the great catch-phrase 'Yabadabadoo' into Far Cry Primal (as far as we're aware), but this submerged nod to the Flintstones is equally satisfying. Dive into a specific lake on the western part of the map, and you'll find none other than a car designed to the same specifications as those used by the Flintstones. With Far Cry: Primal being a decidedly grittier and more realistic world than that of Hanna-Barbera's imagining, it's kind-of feasible that some of the villagers attempted to put together an early form of automotive transport, but ultimately found it impractical to push a hulking vehicle with stone boulders for wheels around the place; hence it's now at the bottom of a lake. After all, why have a Flintstones car when you can tame saber-toothed cats and mammoths at the push of a button?
