Final Product: Attack on Titan: The Basement Truth

Attack on Titan: The Basement Truth is a playable interactive field AVG set in the world of Attack on Titan. You are Mira Kessel — Survey Corps scout, blade, and witness on basement detail. Beyond Wall Rose, the dead district of Shiganshina waits. So does Grisha Yeager's basement, and a history that rewrites every life lost outside the walls.

The story is written live as you play. March with Eren, Mikasa, Armin, and Captain Levi, answer their questions and Captain Levi's orders, and choose whether you swear vengeance, protect the living on the island, or cross the sea as a seeker of truth. Every choice you type changes the log — no two marches into Shiganshina unfold the same.

Game Features

  • Live LLM Narrative — Every scene, every line of dialogue, and every log entry is written in real time by an LLM as you play. Levi's deadpan orders, Eren's burning rage, and Mikasa's quiet devotion all arrive in the moment — no two marches into the basement unfold the same (deepseek-v4-flash real-time narrative).
  • First-Person Survey Corps Scout — You are Mira Kessel, and everything is seen through her eyes: the cold camp, the ruined streets, the weight of a century of lies. Type any action — scout ahead, question a veteran, open a journal — and the story answers in her voice.
  • The Wall-Breaking Cast — Eren, Mikasa, Armin, and Captain Levi march beside you, each rendered as a full-body Survey Corps sprite. Face the dead district together, and let the weight of their histories shape what you find in the basement.
  • Stat-Driven Destiny — Resolve, Trust, and Knowledge meters track Mira's soul. Swear to bring them back alive, promise to dig for answers, or refuse to spend lives for nothing — each intent feeds the story and colors how the basement truth finally lands.
  • Hand-Painted Dark Military Art — Semi-realistic painterly game splash art across every background and sprite: grim olive and ash grays, colossal stone walls, ruined districts, and dramatic overcast light from the camp to the ocean horizon.
  • Browser Playable — Runs directly in your browser, no download needed. Live LLM dialogue on every page turn — march to Shiganshina, save your progress, and keep your blades ready.

Production Process Breakdown

Stage 1: World Buildingclaude-opus-5
AI receives the prompt "Attack on Titan — a dark military fantasy of last-stand survival and buried history" and generates the world — 29 atom cards: characters (8), locations (6), events (5), factions (4), lore (6). Each card carries original descriptions, cover art, and interconnections across the Walls.
Stage 2: Game Design & Artgpt-image-2
AI designs the game from atom cards: writes the story rules for Mira Kessel's basement detail, the scene flow from the cold camp to the basement archive, and generates every art asset — 6 scene backgrounds, the title key art, and 5 character sprites. Each sprite was generated with a full-body sprite prompt, then background-removed to transparent PNG via BiRefNet.
Stage 3: Build & Publishdeepseek-v4-flash
Game built and published with one click, instantly shareable online. The live LLM (deepseek-v4-flash) improvises the story in real time as you play — narrating scenes, voicing Levi, Eren, Mikasa, and Armin, and reacting to every choice you make.
