Indie stealth game Volume will gain a new set of levels via story expansion Coda.
The add-on launches first via Sony's upcoming PlayStation VR and will be available at the headset's launch - whenever that may be in 2016.
Coda will be free to any existing owner of Volume on PlayStation 4 and contains 30 new missions set after the main game's campaign.
But it's unclear if any of the same characters will return - a new cast is set to take up the reigns of Coda's missions instead.
The main game is set to be a Crossbuy title across PS4, Vita and PlayStation VR when it launches.
Volume is also getting a patch today to add new checkpoint modes and user-generated content as picked by the game's staff.
If you haven't played Volume already, the title is currently 30 per cent off via PS4 until 4th November.
"Volume isn't short of great ideas, but it delivers them gracefully, one at a time," Dan Whitehead wrote in Eurogamer's Volume review, "layering simple concepts on top of solid mechanics to create the sort of organic gameplay experience that seems effortless."
