Siren's Rest is now available for PC and consoles, adding an expansion to Still Wakes the Deep, the narrative horror game set on an offshore rig. The Windows edition is on the Epic Games Store and Steam with a 15% launch discount. This is set in 1986, about a decade after the events of the original game (which is required), so pack your Walkman. A new Extended Gameplay Trailer shows the undersea investigation of the disaster. Here's a description, which spoils the ending of the base game:

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.
