A new trailer for Uncharted 4: A Thief's End was released today, and was quickly called out by Ubisoft developers as containing art from Assassin's Creed: Black Flag.

Assassin's Creed head of content Aymar Azaïzia tweeted out a screencap from the trailer (left) that featured a framed piece of concept art from the Ubisoft game (above).

Though Ubisoft declined to comment, Naughty Dog issued a replacement trailer and a statement on the matter:

“In our eagerness to get the story trailer out we made a regrettable mistake and didn’t thoroughly vet the art work used for an in game painting. We’ve already updated the trailer. We hold all artistry in high regard and take full responsibility for having allowed this to happen," the studio said.

“We want to sincerely apologize to everyone at Ubisoft, the Assassin’s Creed team, the original artist, and our fans.”

Aside from the artwork situation, the trailer suggests Uncharted 4 will continue the PlayStation-exclusive adventure series' cutting-edge graphical work.

Uncharted 4 releases April 25 on PS4.
