Say hello to Samuel, brother of the tomb-raiding Nathan Drake, and these siblings are going to cause all sorts of chaos in Uncharted 4: A Thief's End.

Game Informer has gotten a behind the scenes look at happenings throughout Naughty Dog as the studio is putting together the highly anticipated next entry of the Nathan Drake story, Uncharted 4: A Thief's End. Taking place three years after Nate and Elena's wedding ring ending of Uncharted 3: Drake's Deception, Nathan is trying to adjust to a different, quieter life. Of course, the blood of Sir Francis Drake flows through him, and he eventually sets back out on another adventure that starts with archaeological sites and branches out to terrorists, pirates and gunfire.

The big difference in Uncharted 4 compared to Drake's previous games is his company. Uncharted 4 will also star Nate's long lost brother, Sam. As you can tell by the picture, he looks like Nate, but they certainly aren't alike. Even better, legendary voice actor Troy Baker will be voicing Samuel Drake. That's right, Troy Baker and Nolan North will be going back and forth talking to one another throughout Uncharted 4.

While no release date has been set, we can expect Uncharted 4: A Thief's End to launch exclusively on PlayStation 4 sometime by the end of the year. Game Informer is doing a full month of exclusive Uncharted 4 coverage, and here's a trailer for its behind the scenes look at what's going on at Naughty Dog:
