Tainted Grail: The Fall of Avalon, the PC adaptation that turned heads by transitioning from its tabletop roots, has just released its first expansion. To mark the occasion, the base game has surged to the top of Steam’s global best-seller charts, bolstered by a timely discount.

If you're into Arthurian legends twisted into something grim, Tainted Grail: The Fall of Avalon is your poison. Set 600 years after King Arthur’s demise, this first-person open-world RPG drops you onto the island of Avalon, where madness, plague, and mysterious mists are the order of the day. Often dubbed 'Dark Fantasy Skyrim' by fans for its gloomy atmosphere and heavy-hitting combat, the game is currently enjoying its first 30% discount since leaving early access.

The new expansion, 'Sanctuary of Sarras', plunges you into ancient deep-sea ruins. You'll be tracking the legacy of Nimue, the sorceress who dared to challenge Arthur, across a campaign packed with water-themed foes, four boss encounters, and over 20 dungeons. With over 100 new gear items, scaling enemies that match your level, and three new skill trees to overhaul your build, it’s a meaty addition.
