Sniper Elite developer Rebellion has acquired Radiant Worlds for an undisclosed sum.
Radiant Worlds will be rebranded Rebellion Warwick. It joins Rebellion Liverpool and the firm's HQ in Oxford.
Radiant Worlds hit trouble last year after the unexpected shelving of SkySaga: Infinite Isles left the firm without income. Staff were then notified that redundancies may occur across the entire company.
However, Rebellion has rescued the firm and its 70 employees.
Rebellion Warwick will immediately work on the firm's current projects, which include Strange Brigade. The division will also contribute to the creation of Sniper Elite, Evil Genius and Battlezone.
Radiant Worlds was formed in 2013 by development veterans Philip and Andrew Oliver. The pair will remain at Rebellion Warwick.
The new studio takes Rebellion's staff count up to 300.
"To bring such great people to the company, just after our 25th birthday, is quite remarkable," said Rebellion CEO and co-founder Jason Kingsley OBE. "It's been a great year for us and we have a lot of plans to help make 2018, 2019 and beyond bigger and even greater years for Rebellion."
Philip Oliver added: "We've known the Kingsleys for many years and have always had enormous respect for them and the company they've built. We know that our core values of creativity, passion, and ambition are mirrored by Rebellion, and we're excited to be part of their amazing team."
