Leroy Athanassoff has stepped down from his position as creative director of Rainbow Six Siege.

The change was announced in a post on Ubisoft's blog, in which he said that he was making this move due to personal reasons and would be pursuing "other opportunities" at the French publishing giant.

He is being replaced by Alexander Karpazis, who has worked at Ubisoft Montreal for almost ten-and-a-half years. Before being promoted to creative director, he was art director.

"This isn’t a decision I make lightly – I love this game and this community, and I’m so proud of everything our team has accomplished together over the last two years – but I’m confident that it’s the right one, and the team has given me their full support," Athanassoff wrote.

"Don’t worry, I won’t be going too far, and I have a feeling that my journey with this incredible game is far from over."

Karpazis added: "I’m truly thankful for Leroy’s mentorship over the years. He’s taught me what exemplary leadership, creativity, and passion look like in the position of Creative Director. Leroy’s hard work will be visible in future seasons as the team and I prepare for one of the most ambitious years in Siege’s history. I’m extremely humbled by the team’s trust in me, and I hope to earn the trust of the community in my new role as well."

Athanassoff was promoted to creative director at the end of 2019 after the departure of creative director Xavier Marquis and brand director Alexandre Remy.
