• New mechanics center on swim-based traversal with an umbilical tether for air management and a cutting tool to clear rusted obstacles
• The expansion revisits familiar corridors in deep darkness, using flares and environmental storytelling to heighten tension
• Critics commend the voice performances and fresh perspective on the base game’s events but report that the story can be finished in under two hours
• Players encounter technical problems such as invisible helmet visuals, overlapping voice lines, and clipping issues with the air-tether
