Publishing group Sega has acquired Californian indie studio Three Rings, the developer has announced.
Financial terms were not disclosed.
“Today brings to a close a ten year journey as an independent developer, and opens a new chapter for the studio as a part of the Sega family,” said co-founder and CEO Daniel James.
“As many of you know, Sega and Three Rings partnered to launch Spiral Knights, building a deep trust and mutual respect over the past year.”
James added that Sega is now collaborating with the studio to finish its work on a Doctor Who game – a project commissioned to it last year by the BBC.
Three Rings will continue to operate as a self-contained development studio, he added.
“It will continue to be managed by myself and my colleague Tom Schofield. Our talented crew are excited to be joining Sega; we all foresee years of great collaborations ahead. Again, no changes to our current development plans have been made, and we of course hope to announce more exciting projects in the future.”
