Everyone knows exoskeletons are the future of warfare. Call of Duty says so. But this game thinks they’re the saviour of the environment too. Valley [official site] is a first-person science-fiction adventure from the folks that horrified you with Slender: The Arrival. You’re dropped in a mysterious valley hidden among the Rockies and you are encased in the L.E.A.F. suit. This means you can run as fast as wild animals and leap over chasms in a single bound, as the trailer below shows. AND you can bring dead things back to life just by injecting them with a glowing life force (see blue deer above). But should you die and resurrect yourself, the natural world dies too.
