41 Games: Zeno Clash
This game does not have an unoriginal moment or idea in it. It is a compact, striking, alien experience. As if it weren't enough to have an entirely surreal, fantastical setting full of unfamiliar characters and concepts, the story is revealed entirely in flashback.
For the duration of its four-hour play time, I was utterly transported, delighted by each surprising twist and turn. I remember it now in fragments: punch-ups on an alien landscape, a journey down a river, surrounded by snipers, an assassin hurling bombs from the top of a towering alien creature, the Corwids, single-minded, possessed, signifying that the dangers of this journey are not merely physical but psychological.
