About Tainted Grail: The Fall of Avalon
Tainted Grail: The Fall of Avalon is a first-person open-world action RPG developed by Questline and published by Awaken Realms, built on Unity 6 and written by Polish fantasy author Krzysztof Piskorski. It entered Steam Early Access on March 30, 2023, and reached its full 1.0 release on May 23, 2025, for PC, PlayStation 5, and Xbox Series X/S.
The story is set in Avalon, a dark reimagining of the Arthurian mythological isle. Six hundred years after Arthur led survivors from the plague-ravaged Homelands to conquer Avalon and suppress the Wyrdness using Merlin's Menhir totems, the totems are fading, the primordial force of chaos is spreading again, and the Red Death is returning. Players arrive as a stranger in the south of Avalon and are drawn into navigating a fractured land torn between the kingdom of Kamelot, the Dál Riata tribes, and a garrison of soldiers, while uncovering the darker truths behind Arthur's reign.
The open world spans three distinct zones: the misty Horns of the South, the sun-bathed Cuanacht, and the snowy Forlorn Swords. The full game contains over 250 unique, fully voiced NPCs, more than 200 side quests, 70 dungeons, and over 60 enemy types. Player decisions shape faction relationships and story outcomes, with a branching main questline offering dozens of possible endings depending on the choices made throughout the campaign.
Combat supports a wide range of playstyles across melee, ranged, magic, stealth, and hybrid builds. Players can equip two-handed weapons, dual-wield one-handed weapons, use shields, bows, magic spells, throwables, and alchemical mixtures. A depth of interconnected stats, perks, gear, and crafting lets players shape a specific build rather than following a fixed class structure. Supporting systems include fishing, farming, blacksmithing, alchemy, cooking, mining, and home management, all integrated into the open world rather than separated as optional minigames.
At night, the Wyrdness intensifies across the land, changing the environment and spawning stronger enemies, adding a survival dimension to exploration. Tainted Grail: The Fall of Avalon holds a Metacritic score of 80 and a Very Positive rating on Steam.

The comparison comes up frequently due to the shared first-person open-world RPG structure. Both games feature open exploration, character customization without fixed classes, and a large world filled with side quests and dungeons. Tainted Grail distinguishes itself with a heavier narrative focus, morally grey choices with tangible consequences, and a darker, more grounded tone drawn from its Arthurian setting.
The main story, combined with a reasonable amount of side content, takes roughly 50 to 70 hours to complete. Players who pursue all side quests, factions, and optional content can expect to exceed that range significantly given the breadth of the three open-world zones.
Yes. The main questline branches across dozens of possible outcomes depending on player choices, faction relationships built throughout the campaign, and which NPCs survive or are aided along the way. A secret ending is also accessible through a specific extended questline.
Yes. A free demo is available on Steam covering the game's prologue, offering roughly one to two hours of gameplay. It includes the opening sequence and gives a solid preview of the game's tone, combat, and exploration before committing to a purchase.
