Alexander Karpazis Steps Down as Creative Director of Rainbow Six Siege

Alexander Karpazis has announced his plans to step down as Creative Director of Rainbow Six Siege. Alexander is set to depart after the Six Invitational and will see out the reveal of the Year 11 Roadmap.

Alexander Karpazis will be replaced by a new Creative Director, Joshua Mills, who will take on the role when Alexander departs. The pair have worked together for a number of years, with Joshua Mills having also worked on Siege for several years.

Alexander Karpazis departs Rainbow Six

Alexander has been with Ubisfot for nearly 15 years, and has been in the Creative Director role for over four years of those. Though he was part of the Rainbow Six team since 2017, so his departure comes after nine years working on the game. Speaking about his time, Alexander said;

“I am proud to have been a part of the Siege team for the last eight years and a Siege player for even longer. I cannot put into words the number of ways this game has impacted my life; the incredible team that I have been a part of, the work we have achieved together, the adventures I have gone on, and the people I have met along the way have had a profound effect on me and have enriched my life season after season”

Alexander has spent half of his professional career at Ubisoft, though he will remain within Ubisoft. He added, “It has been an honor spending half my professional career working on Siege. This March, Siege will release what I believe is one of the most special seasons we have ever worked on. This moment will mark a high point that I can proudly transition from, to new challenges within Ubisoft. I will be taking with me all the experiences and learnings I have had on Siege and pouring it into something new.”

Joshua Mills will come in to replace Alexander, who has worked as Game Director for Rainbow Six Siege, a role he has held since January 2024, where he was promoted from his role as the Associate Game Director.

“Siege has been part of my life for the past decade, but my love for all things Rainbow begins well before that. I have always been drawn to the high stakes heroics of the franchise, and with my 4+ years on Siege to-date it’s been a dream to have become part of its history.”

Joshua has worked with Ubisoft since he joined the company in 2025, and has worked on Siege, Assassin’s Creed, and at least one unannounced project. Alexander closed by praising his replacement.

“Joshua Mills will be taking over as the new Creative Director on Siege! Joshua and I have worked together for many years. Not only is he a great friend, but he has proven himself to be a strong leader and a champion of Siege values. We have been working on this transition of responsibilities for over a year, and I am confident he will lead this game to even greater heights. I will let him introduce himself in his new role below.”
