This is the best Halo game. It's got layers and layers of atmosphere in a dark, rainy, ruined city (honestly it's a much better noir game than L.A. Noire in setting at the very least, even if the actual mystery clue finding part of it isn't really there), along with a soundtrack that mixes classic Halo fanfare and drums with very dark, low-key piano pieces, punctuated by a brooding saxophone. Beyond the atmosphere, its got Halo 3's gameplay (the best Halo gameplay besides maybe 5, fight me) and a pretty compelling story. It feels great, looks great, plays great and sounds great. And honestly, what else do you need?
