Author and game studio founder Tom Clancy passed away in Baltimore last night. He was 66.

Clancy is best known for military thrillers such as The Hunt for Red October and Patriot Games, many of which were made into films.

However, he also founded game studio Red Storm Entertainment in 1996, which released more than a dozen games he directly endorsed, including a number of Rainbow Six and Ghost Recon titles.

The studio was purchased by Ubisoft in 2000.

"We are saddened to learn of Tom Clancy's passing and our condolences go out to his family,” wrote Ubisoft on its Facebook page.

“Tom Clancy was an extraordinary author with a gift for creating detailed, engrossing fictional stories that captivated audiences around the world.

“The teams at Ubisoft, especially at the Red Storm studio, are incredibly grateful to have collaborated with and learned from him, and we are humbled by the opportunity to carry on part of his legacy through our properties that bear his name."

Red Storm is currently working on Tom Clancy's Rainbow 6: Patriots in conjunction with Ubisoft Toronto and Ubisoft Montreal.
