Mobot: We've already given a perfect score to Asphalt 6: Adrenaline. It's an unashamedly fun, eye-poppingly visceral and breathtakingly brash arcade racer that skimps on realism to deliver massive thrills that are best described as utterly bonkers.
However, it also looks completely pants when blown up on an iPad. Which is where the HD version comes in. For a slightly higher price tag, you'll be able to net an optimised experience that looks great on the bigger screen. But is it worth the upgrade?
