The best thing about the Halo 5 gameplay trailer is the story doesn't immediately collapse into sci-fi non-sense; this is a coherent elevator pitch. The people our hero, Master Chief, rusted have asked him to do something outside his moral boundaries, and he's gone rogue. Now, a band of four soldiers must travel across a hostile galaxy to capture the warrior of their time. Either that's the story or it's something close to it. Either way, the trailer alone offers a coherent through-line than the previous Halo games, each of which I've played multiple times, and vaguely remember having something to do with space politics, a floating space ring, something call the Hive, and clone babies. Following along required a patience for text-heavy in-game computer terminals and loopy dialogue.
My only issue with the Halo 5 trailer stems from a gut-feeling that the most interesting computer animated bits we see today won't quite be as over-the-top as playable chunks in the game. This trailer promises high-speed snow-skiing death ballet, and I hope that's what I get instead of a slow-paced bullet fest that's just like any other shooter corridor but on a horizontal decline. Actually, I hope for two things from the actual gameplay: more snow-skiing firefights and less Muse.
