In Still Wakes the Deep, horror comes in multiple forms. Violent creatures stalk the walkways on thin, too-long limbs that burst from their bodies like snapping bungee cords. Human-sized pustules and bloody ribbons grow along the corridors, emitting a sickly cosmic glow. The ocean is an unrelenting threat, wailing beneath every step. And then there’s the Beira D oil rig itself, a massive and mazelike industrial platform supported by slender tension legs in the middle of a raging sea, groaning and tilting as it’s ripped apart from the inside. Each of these elements is deadly; each one manifests a unique brand of terror.
