Avalon is alive with various supporting activities that enrich your journey. Participate in sketchbook journaling, fishing, farming, blacksmithing, alchemy, cooking, mining, managing your house, and more.

At night, the Wyrdness—a chaotic primordial force—descends upon the land, altering reality and introducing survival challenges. Your foes become even fiercer, leaving no place for mistakes or hesitation. Kill or be killed.

Confront morally ambiguous choices that will test your character and shape Avalon’s future. Follow the dark legacy of King Arthur Pendragon while engaging with over 250 NPCs and tackling 200+ side quests.

The game doesn't have AI. The only "proof" People have is that in a 2D PICTURE you can only see 2 fingers. Most likely the other 3 are on the other side. Actual idiots. Their just mad a new Indie company can make a game better than their translop companies can. Its sad to see how brainwashed and ret@rded people have become now. If it had AI, there would be a warning or whatever you like to call it on the steam page. Which it doesn't.
Muy recomendable. Juego realizado con mucho amor por parte del estudio Questline. Periódicamente publican pequeñas expansiones y añadidos gratuitos. Están muy encima del juego, escuchando a la comunidad. Si quieres algo parecido a Skyrim pero con su personalidad, aquí lo tienes.........
Horrible level design and quests just made to waste you time .. story is meh .. but the vibe of the game is nice
it's just skyrim but better in almost every way this game should be used as an example by bethesda for what they could ve making
I've enjoyed this game without needing 1.21GB of Mods that don't even add anything, just fix broken content and poor deployment. I also managed to actually enjoy the storyline. I like the characters. The combat is really good, specially with the new changes, even if you can turn them off if you wish, which by itself is really nice. The Devs really seem to not only care about their game, but also the people playing it. This game deserves you to at least try it.
Fantastic first-person RPG (w/ 3rd person support) in a really unique and rich world setting. The amount of free-DLC the devs have been putting out for this game is insane and deserves a special callout for this, on top of it being a quality game already. You can tell the dev team cares for the game and those playing the game, and I am wholeheartedly happy supporting a team that's so game and gamer first focused.
20hr in, love this game, great mix between story, lore, challenging combat and character diversity, dev team has been very active in fixing the bugs, and have only experienced one very minor graphical glitch which ficed itself quickly. Game is kind of a mix between dark souls and elder scrolls, pulling in the best aspects of both those genres. Highly recommend.
Душная, платная сборка на скайрим. Ощущение будто собрались 2 подпиваса и собрали из готовых ассетов игру, выкрутив сложность и паллернув квестами "принеси-подай не мешай"
相较于市场上越来越多的类魂游戏,我更希望厂商们能像《污痕圣杯》一样,做更多类《上古卷轴》的游戏
Just had its 4th free bonus DLC. They keep improving this single player game while providing free content more than a year after release.
