Burning Shores is every bit the continuation of Horizon Forbidden West. It builds on the great gameplay of the base game with a few new wrinkles, introduces a watery world and the ability to dive into it, and moves the story downfield a few yards as Aloy and her allies, old and new, prepare for what comes next. You won't be lost having missed out on this DLC when the next full game does arrive, but you would have missed an opportunity for hours of fun in an excellent world that is worth the time of any Horizon fan.
