Sony announced today that indie shooters Blacklight: Retribution (above) and Primal Carnage, both already available on the PC, will also be turning up on the PlayStation 4 when the console is released later this year. Like The Witness, these games will be self-published by developers Both Zombie Studios and Lukewarm Media respectively. Also announced, rather quietly, is the fact that indie death simulator Limbo will also be appearing on a Sony console, with a Vita release due "later this year".
