Whip out your Sony studio boss bingo sheet, as yet another high-profile developer has bit the dust. The latest in the long line of executives to exit the manufacturer is Justin Richmond, who was acting as Uncharted PS4’s game director. His departure follows in the footsteps of Amy Hennig, who worked as the creative director on all of Nathan Drake’s escapades.

“I have in fact made the decision to leave Naughty Dog,” he told IGN earlier today. “I love the company and the people, and know that they will continue to create awesome games going forward. On a happier note, after careful consideration and exploration, I have joined Riot Games. There is some really innovative stuff going on here that I can't wait to be a part of."

Richmond has been with Sony's premier studio since 2008, and started out working on Uncharted 2: Among Thieves’ multiplayer mode, before stepping up to the role of game director on Uncharted 3: Drake’s Deception. Much like with Hennig, the Japanese giant has stressed that this news won’t affect the development timeline of its next-gen sequel.

In truth, it’s likely that the departing developer’s work is complete, with the direction of Uncharted PS4 more or less set in stone by now. The timing of these departures is starting to look bad, though. Are you worried by the current exodus at Worldwide Studios, or do you think that it’s all just an unfortunate coincidence? Let us know in the comments section below.
