Some details have appeared with regards to Uncharted 4 after it was featured in this month's Game Informer.
According to the magazine, Uncharted 4 is set three years after the end of Uncharted 3: Drake’s Deception, and sees Drake return to treasure hunting after his long lost brother Sam arrives on the scene.
Sam will be controlled by AI, although he's not quite as skilled as Drake at getting around, so this will be seen to cause tension between the two during the game.
The two brothers certainly get around, first heading to the mythic Madagascar colony founded by pirates: Libertalia and over the course of the game, heading through urban and snowy environments. The brothers will also find themselves up against rival treasure hunters known as Rafe and Nadine and of course, interference from villains.
According to the preview, environments will be less linear and Drake will have new abilities.
Uncharted 4 is expected to arrive later this year, which is great news as it's your most anticipated title.
