Bungie and Sony were collaborating long before the two companies announced console-exclusive features for Destiny on PlayStation.
Bungie's head of community Eric Osborne told TechRadar that Sony was "a really good partner" ever since Bungie first considered releasing on next-gen consoles.
"We really didn't know where anybody was going, but it became really clear talking with Sony at the outset that their vision really aligned with where we wanted to go," Osborne said.
The relationship extended both ways, with Bungie even playing a part in the physical design of PS4 - which is of particular note considering that the studio was owned by Xbox creator Microsoft up through 2007.
"They worked with us, of course, on core systems and the controller itself - making it better for shooters, helping improve that for players, helping include and improve the social aspects of the game," Osborne said.
On Bungie's side, Destiny on PS3 and PS4 will include an exclusive co-op Strike mission set on Mars, an additional competitive multiplayer map, and a selection of exclusive guns, gear, and ships
The game will release exclusively on PS3 and PS4 in Japan.
