Uncharted 4: A Thief’s End, Naughty Dog’s long-in-development PlayStation 4 exclusive that was at one time scheduled to debut in 2015, has “gone gold.” That means development on the base game is finished and discs are now headed to manufacturers for mass-production ahead of the game’s May release date.

Naughty Dog shared the news today on Twitter.

It’s been a long road to release for Uncharted 4. The PS4-exclusive was first scheduled to launch in 2015, but was later moved to March 2016 and then again to April 2016 before its latest delay to May 2016.

Uncharted 4 is the final entry in the series that Naughty Dog plans to develop and the last one to feature Nathan Drake in the lead role. However, the series may live on with another developer.

Uncharted 4 director Neil Druckmann shared this picture of what appears to be one of the first discs with the full game on it. Check it out:

Additionally, the game’s other director, Bruce Straley, said in his own tweets that Uncharted is is possibly the “most visually stunning game ever created” and the best Uncharted ever.
