Outlandishly difficult, horrifically intense in the best possible way, and beautifully alive. It sets an ominous chord from the moment you slide out of a drainage pipe into the industrial wastes that hangs over your trek through the desolate, overgrown cityscape of its world. The sewers sloughing into orange dust, the mountains of garbage home to a dying ecosystem, the crypts that survive a land no longer for them. It's gorgeous and intriguing and as brutal and daunting as it can often be, it gently prods you to try again, and again, and again. I will play this game forever.
