Still Wakes the Deep DLC

Still Wakes the Deep: Siren's Rest is a downloadable expansion for the base game on PC. It adds a new narrative chapter set in 1986, ten years after the original rig disaster. Players take on the role of Mhairi, leading a saturation dive team to the wreck of the Beira D. A Steam account and the base game are required to play.

Narrative capacity and limits

The DLC delivers a focused first-person narrative adventure that continues the horror story in the North Sea. It explores the fate of the 1975 crew through new environments and precision-tool gameplay. The experience ends when the narrative concludes; it does not add separate modes, multiplayer, or open-ended replay systems beyond the story content.

Build integration and requirements

Activation uses a Steam online game code and is restricted to select countries listed in the specifications. The product requires a 64-bit Windows system and the base game installed via Steam. No additional hardware peripherals or platform subscriptions are needed beyond the Steam client and an internet connection for activation.

Questions about this item

Will the Siren's Rest DLC run on my existing PC if it meets the base game's 64-bit Windows requirement?

Yes, the DLC requires the base game Still Wakes the Deep on Steam, which already needs a 64-bit processor and operating system, so no extra hardware is needed.

How can I verify the DLC activated correctly after entering the Steam code?

Open your Steam library, locate Still Wakes the Deep, and check the DLC section — Siren's Rest will appear as installed once the download finishes.

Does the 84306 code include the base game Still Wakes the Deep or only the expansion?

The code delivers only the Siren's Rest DLC; you must already own or purchase the base game separately on Steam to play.
