Sony Computer Entertainment America LLC (SCEA) today introduced several titles from its independent developer portfolio for all PlayStation platforms, including the PlayStation 4 system. "We've got an incredible team on the ground that talks to developers every day, and these new games we're announcing are a direct result of the team's proactive outreach and focus on working with top independent developers," said Adam Boyes, vice president, publisher and developer relations, SCEA. "Our process and approach in working with developers has evolved to incorporate a lot of flexibility into the process, including the way we pursue and discover new talent, help them with funding solutions and work together to deliver their best games onto PlayStation platforms."

The games unveiled today for PS4 include Zombie Studios' Blacklight: Retribution and Primal Carnage: Genesis from Lukewarm Media. These games will join Jonathan Blow's exploration-puzzler, The Witness, as self-published titles making their console debut on the PS4 system. In addition to supporting Blacklight: Retribution, the PlayStation Pub Fund, which provides back-end financial and marketing support to developers, adds fighting game Divekick and infographic adventure Metrico, which is a PlayStation Vita (PS Vita) exclusive.
