Developer The Chinese Room and publisher Secret Mode have released the latest expansion for Still Wakes the Deep. The newest expansion, Siren’s Rest, is available to purchase for $12.99 on PC via Steam and Epic Games Store, Xbox Series X|S, and PlayStation 5.

Siren’s Rest is set over a decade after the events of Still Wakes the Deep and follows a diving crew as they explore the wreck of the Beira D oil rig, using a crowbar, cutting torch, and camera to unearth the final moments of the crew. Featuring an original story led by an all-new cast, Siren’s Rest is a chance to see the Beira D tragedy in a new light, and discover what still lurks in the darkness.

Still Wakes the Deep: Siren’s Rest also features an all-new cast that is led by Lois Chimimba (Doctor Who) as Mhairi, co-starring Lorn Macdonald (Bridgerton, The Lazarus Project) and David Menkin (Final Fantasy XVI, Alan Wake 2), with Kate Saxon directing.

Here is an overview of Still Wakes the Deep: Siren’s Rest:

1986. The Beira D is now a groaning steel catacomb interred in the inky depths of the North Sea. What really happened that December day in 1975, when communications to the mainland were severed and the rig sank without a trace? What answers can be given to families who still grieve, ten years on?

You are Mhairi. And you will find those answers. As the leader of a saturation dive to the wreck of the Beira D, you descend, a fragile light in the crushing dark. Your mission: uncover the fate of the crew and recover what remains of their passing.
