Evaluation
King Arthur: Legion IX launched on Steam on May 9, 2024 as a complete, standalone tactical RPG with 15 handcrafted missions and a self-contained story. Two hotfix patches shipped on May 10 and May 15, 2024 to address bugs shortly after launch, and the only DLC released was a soundtrack on July 26, 2024 — no gameplay content. On April 14, 2025, NeocoreGames announced a console release (PlayStation 5 and Xbox Series S|X) for May 6, 2025, but this was a platform port rather than new content for the game. No roadmap, expansion, or future content has ever been announced. There are no unreleased DLC entries on the store. The last developer communication was the April 14, 2025 console announcement post, and no updates of any kind have followed since then. The game appears to have launched as a finished product and received no post-launch content additions beyond bug fixes and a soundtrack DLC.

About this game
"This title is going to be great if you enjoyed Knight’s Tale, which a lot of people did, or you want a Roman themed campaign!” - Mortismal Gaming
King Arthur: Legion IX is a turn-based, character-centric tactical RPG in the King Arthur: Knight's Tale universe - a dark fantasy version of the Arthurian myth. King Arthur: Legion IX welcomes new players to the mythical land of Avalon with an all-new story and heroes, also offering tough challenges to returning veterans.
A new threat looms over Avalon as the long-lost, infamous Ninth Legion of Rome has set foot on the mythical island. Their commander, the fallen hero, Gaius Julius Mento was granted a demonic legion by their dead emperor, Septimus Sulla to find a way out of Tartarus. But when they accidentally arrive to the magical realm of the Lady of the Lake, Gaius Julius Mento decides to subjugate the island and establish Eternal Rome there. First, however, he must gather his lost legion…
Play through a Roman-themed campaign as Gaius Julius Mento, a tribune of the undead Ninth Legion, as he discovers Avalon. Battle the monsters of nightmares, challenge the Pict tribes, the monstrous Fomorians and the cunning Sídhe. Experience the might of the Old Faith and Christianity and face the knights of Sir Mordred's Round Table through 15 handcrafted missions.
Find, rebuild and protect the remains of the only Roman colony in Avalon and choose your path to victory. By the end of the campaign, you'll have to choose: do you want to become a powerful demon, or will you reject the might of Emperor Sulla and restore your humanity?
