Jacob Jones and the Bigfoot Mystery is an unexpected use of Unreal Engine 3: it's a Professor Layton-style puzzle game, for one thing, instead of any variety of shooter. It stars a group of kid campers, designed to resemble vinyl toys, instead of tree trunk-sized men. And it's for Vita!
Basically, Epic should be using this game to demonstrate the flexibility of the engine.
Lucid Games' new puzzler is the story of a shy kid who goes off to summer camp, and is miserable, until he discovers Bigfoot! Then something something puzzles.
