Game Overview
Avalon becomes a battlefield for Rome’s damned in this grim tactical RPG, where the lost Ninth Legion emerges from Tartarus and finds a new land to conquer. You command Gaius Julius Mento, a fallen tribune whose undead soldiers serve an emperor’s demonic bargain, yet his ambition to build an Eternal Rome collides with a land of Arthurian knights, fae, monsters, and warring faiths. King Arthur: Legion IX tells a self-contained story within the Knight’s Tale universe, so newcomers can follow its Roman campaign without prior knowledge. Its mood is oppressive and morally thorny, trading heroic Camelot romance for mud, ruins, occult power, and difficult compromises.
Missions revolve around leading a compact party of five or six heroes through carefully designed tactical encounters, with positioning often deciding more than raw damage. Cover, flanking, traps, overwatch, opportunity attacks, and character abilities make each turn a problem to solve, while Ultimate and World abilities provide powerful options when a fight turns ugly. Six recruitable undead heroes develop through individual skill trees, equipment choices, crafting, and plentiful artifacts, allowing teams to lean toward control, durability, burst damage, or support. Between expeditions, Nova Roma acts as a resource-starved headquarters: rebuilding its facilities improves the legion, but investments require meaningful trade-offs; several difficulty settings also accommodate either narrative-focused players or demanding tacticians.
What separates Legion IX from a standard squad tactics campaign is its fusion of XCOM-like battlefield planning with a darker, party-driven RPG structure and a striking Roman perspective on Arthurian fantasy. The campaign spans 15 handcrafted quests rather than an endless procedural war, keeping its focus on story momentum, tailored encounters, and Gaius’s gradual choice between reclaiming humanity or embracing demonhood. Heroes avoid permanent death at mission’s end, encouraging experimentation, though careless play can still leave a squad badly weakened and underprepared. Fans of King Arthur: Knight’s Tale, Warhammer 40,000: Chaos Gate, or tactical CRPGs that reward deliberate builds should feel at home, while its standalone cast makes it a solid entry point for patient newcomers.
