“As you may have noticed, our team is going full steam ahead by not only providing support for developers on our current platforms, but also for those working on next-gen titles. We’re expanding our indie support for PlayStation 4 with games like Primal Carnage: Genesis and Blacklight: Retribution, which will join titles like The Witness to ensure you’ll have great indie game experiences on our next gaming console,” Boyes said.

“This recent influx in developer support for PlayStation has come through our continued effort to create a flexible and developer friendly environment. We’re also focusing on burgeoning platforms like PlayStation Mobile by offering Unity support, coming later this year, to make it easier than ever for developers to bring their games to PlayStation-certified Android devices and PS Vita.”
