The Witcher 3: Wild Hunt, Polish developer CD Projekt Red’s highly anticipated open-world role-playing game, has finally gone gold. That means development on the game, which its developer calls its “most ambitious endeavor to date,” is complete ahead of its release next month across Xbox One, PlayStation 4, and PC.

The milestone is particularly noteworthy, given that The Witcher 3 had been delayed a couple of times.

Originally, it was due to launch at the end of 2014 before being shifted to February 2015. After promising “no more delays,” CD Projekt Red did just that, moving the game again to its current release date: May 19.

“We worked so damn hard over the past three years to bring you this game,” CD Projekt Red boss Adam Badowski said in a statement. “From the corrupt nobles in Novigrad to ancient monsters lurking in deep forests, to the bustling cities, colorful ports and breathtaking vistas; all the people, all the places–we literally spent tens of thousands of hours to turn all that into an adventure that will kick your ass and make you want to come for more.”

Now that development has wrapped on the main game, CD Projekt Red won’t just be sitting by idly. Recently, CD Projekt Red announced two major expansions for the role-playing game that will add around 30 hours of gameplay to an already massive title.

And just yesterday, UK retailer Game revealed a special Witcher 3 Xbox One bundle, though it’s unclear if this will also come to the United States.
