Still Wakes the Deep: Siren's Rest is out today, June 18, 2025. The Chinese Room and Secret Mode shipped the paid story expansion on Steam, the Epic Games Store, Xbox Series X|S, Xbox on PC, and PlayStation 5, exactly one year after the original North Sea horror game launched. It is a short, single-player epilogue, not a new game. You need Still Wakes the Deep. The official pitch is a 1986 saturation dive to the wreck of the Beira D, the oil rig that lost contact with the mainland in December 1975 and then vanished.
What Siren's Rest Actually Is
Siren's Rest puts you in the dive suit of Mhairi, leader of a salvage crew sent to recover what remains of the Beira D and give families something more than a dead radio. Official copy sets the year as 1986, a decade after the original story. The rig is no longer a workplace. It is a steel wreck on the seabed. The Chinese Room is treating this as a second chapter for a game that already won three BAFTA Games Awards on April 8, 2025: New Intellectual Property, Performer in a Leading Role for Alec Newman, and Performer in a Supporting Role for Karen Dunbar. Siren's Rest does not restage Caz's night on the platform. New lead, new year, new job. Lois Chimimba plays Mhairi. Lorn Macdonald and David Menkin round out the new voice cast. Kate Saxon is back as performance director. John McCormack returns as creative director. The new story is by Sagar Beroshi and Emma Beeby.
What You Do on the Dive
Gameplay stays first-person and close. You move through the underwater wreck with a cutting torch, a crowbar, and a camera. The work is salvage: cut a path, force a door, photograph what the crew left, and reconstruct their last hours. Secret Mode's launch copy is blunt about the tone. The wreck is not a quiet grave. Something in the dark is still interested in visitors. If you played the original, you already know this studio prefers atmosphere, Scottish voices, and tight spaces over a huge combat sandbox. Expect that design again, now with more swimming and less walking the decks. It is still a single-player story. There is no co-op dive. The original game is a 1975 Scottish oil-rig horror story about an electrician trying to survive after something in the North Sea gets into the crew. Siren's Rest assumes you already care about that incident. The official DLC description even warns that its premise spoils the end of the base game. Play the 2024 campaign first.
Price, Platforms, and How Long It Lasts
Siren's Rest launched for $12.99, £9.99, or €12.99. Steam has a 15 percent launch discount. Secret Mode listed the chapter at about 1.5 to 2 hours. That is an evening for fans, not a second full campaign. You must own the base game. The expansion will not run on its own. Still Wakes the Deep is also on Game Pass for console and PC as of today. Siren's Rest is a separate paid add-on. A Game Pass install of the original does not automatically include the DLC.
Should You Buy It Today?
Buy it today if you finished the original and still want one more look at the Beira D. The hook is a new lead, a wreck instead of a living platform, and a short story built to close the loop rather than restart the series. Skip it, or start with the 2024 game, if you have not played Still Wakes the Deep. This chapter is written for people who already know why the rig going silent matters. At this price and length, it is a fan epilogue. It is not a reason to join the series cold.
