Tainted Grail: The Fall of Avalon - Adventure Pack delivers a single-player open-world RPG experience on Xbox Series X|S. Players step into a dark fantasy setting drawn from Arthurian legends, where they shape events in a world marked by strife six centuries after King Arthur's fall. The bundle combines the base game with the Sanctuary of Sarras expansion for a complete package focused on exploration, narrative choices, and character development.
Gameplay
The core loop centers on free-form exploration across three large zones without guided markers or linear paths. Players navigate on foot or horseback, uncovering points of interest, caves, villages, and hidden locations while managing a day-night cycle. At night the Wyrdness descends, heightening enemy aggression and altering encounters. Combat blends first-person and third-person perspectives with melee weapons, bows, magic spells, and throwable items. Hits carry weight, parries and blocks feel responsive, and builds evolve through six core attributes that influence damage, stamina, health, and more. Skill trees exceed twenty in number, rewarding repeated use of specific abilities, while gear imposes stat requirements and supports mixing light, medium, or heavy armor. Side quests number in the hundreds and feature voiced characters with meaningful dialogue trees. A full playthrough of the base content typically spans 50 to 70 hours depending on thoroughness.
Game Modes
The game operates as a single-player campaign with a branching main storyline and extensive side content. No separate multiplayer modes exist. Challenge Mode serves as an optional difficulty variant available only on new playthroughs starting from Act 1. It introduces permanent debuffs that intensify as the player progresses, functioning like a roguelike layer on top of the standard experience. Recent patches have added support for unarmed combat as a fully viable build path complete with its own weapons, armor category, and dedicated skill tree.
Story and World
The narrative reimagines Arthurian myth in a grim setting plagued by the Red Death and the encroaching Wyrdness. Players awaken in an asylum and gradually piece together their role in the legacy of King Arthur while navigating factions with conflicting goals. Decisions carry weight across the main quest and numerous side stories. The Sanctuary of Sarras expansion adds a self-contained 10-to-15-hour storyline set in a submerged realm. It follows the trail of Nimue and rebel deserters, revealing details of their disappearance and Merlin's retribution. Access requires reaching Act 2 in the base game, after which players explore ancient underwater structures, meet new characters, and confront fresh adversaries.
The Sanctuary of Sarras Expansion
This first major expansion introduces over twenty hand-crafted dungeons and interiors, four epic bosses, twelve new regular enemy types, and more than one hundred pieces of equipment including armor sets, weapons, rings, amulets, relics, and spells. A new progression system revolves around activating sacred shrines that weaken local enemies and grant points for three distinct skill trees. Players can switch the active tree at any time to adapt builds on the fly. Enemies in the expansion scale to the player's level, maintaining tension throughout the underwater zones.
Is It Worth Playing?
Reception has been generally favorable, with Metacritic scores in the mid-70s on Xbox Series X|S and Steam reviews holding Very Positive status after more than a year of post-launch support. Critics and players praise the atmospheric world, narrative depth, and build variety while noting occasional technical issues, janky animations, and uneven difficulty. Ongoing patches continue to improve performance and stability, including Xbox Play Anywhere functionality and free content drops such as the Fists of Fury update. The Adventure Pack suits players who enjoy deliberate single-player RPGs with strong exploration and customization, particularly those tolerant of indie-scale polish in exchange for ambitious scope and frequent updates. Those seeking polished AAA presentation or multiplayer features may find the experience less ideal.
