The latest trailer of Uncharted 4: A Thief's End certainly looks amazing, but there's something peculiar that some Ubisoft staff members noticed in the trailer. Apparently, the trailer contains concept art from Assassin's Creed IV: Black Flag.
Assassin's Creed's head of content AzaÃ¯zia Aymar was the first to notice this, as he pointed out the similarities on Twitter. "Woooow Uncharted 4 using one of ACIV artwork in their trailer... I get the "thief" title now!", said Aymar.
You can compare the Assassin's Creed IV concept art and the scene for the Uncharted 4 trailer in the images below. If you look closely, you will notice that both are undeniably similar, with the only difference being the pirate that's present in the concept art from Ubisoft's title.
Naughty Dog and Ubisoft have yet to say anything on this situation.
