Sony has ended its relationship with PlayStation All-Stars Battle Royale creator SuperBot Entertainment.

Support for the game along with any future DLC will be handled by Sony's Santa Monica studio.

"Sony Computer Entertainment can confirm that the working agreement with developer SuperBot Entertainment has amicably ended," a Sony representative told Kotaku.

"We have had a positive working relationship with this talented studio, and wish them the best of success in their next endeavor.”

An estimated 20 staff were made redundant at Superbot two weeks ago, but the company’s director of operations David Yang hinted that further cuts may be necessary.

"We don't have a reduction plan as of yet, however it is unlikely we can continue with our current work force for an extended period of time," he said.

"We are still working things out and hope to continue on with as many of us as possible."

“We are extremely grateful to have had the opportunity to work on with Sony on Playstation All-Stars Battle Royale, and are extremely proud of the work we have done,” Yang added.

SuperBot was founded in 2009. Its sole release to date is PlayStation All-Stars Battle Royale for PlayStation 3. Bluepoint Games developed the Vita version.
