The Vanishing of Ethan Carter throws you into the deep end of a supernatural mystery without any mechanical or narrative guidance whatsoever. Naturally, the game's first half hour or so is a fairly disorienting experience, one that saw us avoiding manmade traps in a forest, solving a super-grisly murder, chasing a holographic astronaut and then traveling into the far reaches of space. It's a completely bonkers way to start playing a video game, and you can check it out in the long gameplay video posted above.
