The Last of Us was a success when it was released on PS3, and with the game launcing on PS4 the following year, speculation began that there was a sequel in development. However, with game directors Bruce Straley and Neil Druckmann taking over Uncharted 4: A Thief's End and Naughty Dog revealing that all other project had been "put on ice", it became aparant that the desired sequel wasn't in the works, at least yet.
In a recent interview with GamesRadar, Druckmann revealed that he and Straley were working on "prototypes" for The Last Of Us universe, as well as other projects outside The Last of Us, before jumping to Uncharted 4. He added that their current focus is the development of the Uncharted 4 single-player DLC, with all other projects coming only after this one is finished.
"Before my partner, Bruce [Straley] and I, my directing partner, came on to Uncharted 4 we were working on prototypes for different ideas within The Last Of Us universe," Druckmann told GamesRadar." Without going into specific genres [there were] ideas outside the The Last Of Us."
"All those things were left on hold when we had to come onto Uncharted 4 to direct the project. Our next focus is the single player [Uncharted 4] DLC and then, once we have enough resources, resurrect all those prototypes; see where we're at, see where the teams at, what they're excited for and go from there."
Uncharted 4: A Thief's End releases worldwide on the 10th of May.
