Revision History

Removed the unsupported claim of Hellwalker-exclusive rewards, corrected the AI description (behaviour trees, shared with Sixty-Six Days, no weapon resistances) and the per-boss new-move claim, and fixed a launch-tense phrase

Added the director's October 2026 figures for Hellwalker's stat increase and how its AI is built, and that no one on the team has cleared Sixty-Six Days without dying, and corrected the key details table headers

Corrected the difficulty gating: Hellwalker is selectable on a first playthrough and only Sixty-Six Days requires New Game Plus

Updated to the current four-tier difficulty set: renamed Gamechanger to Pathbreaker, added Sixty-Six Days, and corrected which tiers are New Game Plus only

Rewrote 1 image alt text to describe what each screenshot actually shows instead of a numbered placeholder

Corrected wikilink existence flags

Added a gameplay screenshot after the first section heading

Expanded Hellwalker Mode with sections on stylistic-mastery framing, per-boss AI adaptation including Huangxing's situational decision loop, and the NG+-only rationale

Updated internal wikilink hrefs after slug corrections

Convert bullet-point lists to tables for better readability

Enhanced with all three difficulty mode names and NG+-only unlock details from S-PARTY 2025
