“This is as close as I could get us,” says Cortana, your A.I. companion not long after Halo 4 begins. “Hope you don’t mind hoofin’ it a little.” This explains a lot about Halo 4 and the Halo series in general. You’re never very close to where you’re going, because, well, what fun would that be? It has a price, of course, the story twisting and conforming to serve the game, every route the longest one, every puzzle an excuse to send you through gauntlets of aliens. And yet that’s what we love about Halo, and Halo 4 does it better than any game since the original, adding some of the shrewdest enemies (the Prometheans) the series has yet seen.
