Unity has made its popular Unity Pro game engine free for all licensed PlayStation developers.
Unity currently supports PS3, PS4 and PS Mobile platforms.
Ganes set to come to PlayStation platforms using the Unity engine include Assault Android Cactus, Night in the Woords, Shiftlings and BroForce.
"This is another amazing display by SCE of how much they welcome developers, no matter their size and pedigree," said Unity CEO David Helgason.
"Some of the most exciting games are coming from smaller teams who in the past would have been hard pressed to get on so many awesome platforms."
