Jeff Kaplan, the most public face of Blizzard’s team shooter Overwatch, has left the organization.

In a letter posted today, Kaplan said “it was truly the honor of a lifetime to have the opportunity to create worlds and heroes for such a passionate audience. I want to express my deep appreciation to everyone at Blizzard who supported our games, our game teams, and our players. But I want to say a special thanks to the wonderful game developers that shared in the journey of creation with me.” It’s not satisfactory where Kaplan is going, yet his residency at Blizzard lasted 19 years.

It’s additionally unclear how could affect Overwatch. The game is in a bizarre spot right now, with a sequel in the work that isn’t relied upon to launch until after this year. Aaron Keller, portrayed as a founding member of the Overwatch team and a 18-year Blizzard veteran, will be taking over Kaplan’s role.

In an explanation, he expressed: “Jeff’s been a great leader, mentor, and friend, and he knows how much we’re going to miss him. I’ve been lucky to work alongside him and the rest of the Overwatch team for many years in building something that continues to inspire people all around the world, and I’m honored to carry the torch forward.”

He added that “development is continuing at a good pace” on Overwatch 2 and that “we’ll be sharing more frequent updates about Overwatch 2 progress and new features in the live game with you all very soon.”
