Umbra Protocol – Style Training — An AI Stylish Action Game from Neta Studio
Play Umbra Protocol – Style Training, an AI-generated stylish character-action tutorial. Master gun-fu combos, dodge into Witch Time and climb the Style Rank from D to SSS against Training Puppets, Agile Shades and Armored Drones — playable right in your browser on desktop and mobile.
Final Product: Umbra Protocol – Style Training
A stylish character-action tutorial where guns are built into your hands and your heels — and every move you make is judged from D to SSS.
Umbra Protocol – Style Training is a playable, landscape-mobile action game generated by AI from a single sentence. You are a newly awakened Umbra Witch demon-hunter hybrid in a sleek circular underground training chamber: a floating virtual joystick on the left, a staggered action cluster on the right, and an instructor who expects style, not survival.
Hold GUN to fire while you move, tap STRIKE for rapid combo strings, hit KICK so your shoe guns fire on contact, and flick-DODGE at the last instant to freeze time in Witch Time. Chain varied attacks to push the Style Rank from D to SSS against Training Puppets, Agile Shades and Armored Drones — then pass the final style exam.

Game Features
- Live LLM Narrative — every beat of the Umbra Protocol was directed by AI: the one-line seed became the world, the neon training chamber, the three enemy types and the style-combat loop itself, designed live by an LLM as the game was built (deepseek-v4-flash real-time narrative). From one sentence to a finished, playable action game.
- Gun-Fu Combat System — guns built into both hands and both high-heeled boots. Hold GUN to fire continuously while moving or mid-combo, tap STRIKE for melee strings, and land KICK so the shoe guns fire on contact — a Bayonetta-style weave of bullets, boots and flair.
- Style Rank Meter — every move is judged D → C → B → A → S → SS → SSS. Varied combos, air attacks and Witch Time punishes raise the rank; getting hit or spamming one input drops it. Big letters pop in top-center with an instructor callout on every change.
- Perfect Dodge & Witch Time — flick-and-hold the joystick (or tap the dedicated dodge button) at the last moment to trigger Witch Time: the world slows into desaturated slow motion and your enemy is helpless. Learn the punish window step by step, then use it to survive.
- Three Enemies, One Arena — slow, heavily telegraphed Training Puppets teach timing; Agile Shades force active dodging and perfect Witch Time punishes; Armored Drones need a Witch Time punish or a full Burst gauge to break. The final exam throws all three at you at once.
- Mobile Touch Controls — a Call of Duty: Mobile-style landscape layout: floating virtual joystick bottom-left, staggered action cluster bottom-right with STRIKE, KICK, GUN, JUMP, BURST and DODGE. Toggleable AIM ASSIST and COMBO ASSIST ease newcomers into the fight.

Production Process Breakdown
From a one-line seed — a stylish action tutorial hybridizing Bayonetta-style and Devil May Cry-style combat for landscape mobile touch — the AI expands the world into a full design package: a Call of Duty: Mobile-style control scheme, the D → SSS Style Rank system, Perfect Dodge and Witch Time, three enemy types and an 8-step tutorial flow that ends in a style exam.
The visual direction locks to a dark high-tech occult look: neon-red and silver lighting, a sleek circular underground training chamber, floating platforms and a giant Style Rank hologram — with every HUD element placed in landscape safe zones clear of the thumbs.
Two 16:9 versions of the arena are generated — the main training chamber with the glowing Style Rank display and a wider cinematic establishing shot of the same space, crimson and silver volumetric light — both kept free of characters and UI so the gameplay layer sits on top.
Full-body character art is generated on clean white and green-chroma backgrounds — the Umbra Witch hero in idle, punch, kick, dual-gun and dodge poses, the instructor portrait and the three enemy types — then cut to transparent PNG via BiRefNet for the runtime.
The engine is assembled in the browser: floating joystick and staggered action cluster, enemy AI for puppet, shade and drone, Style Rank evaluation, Witch Time slow-motion, the Burst gauge, assist toggles and the step-by-step tutorial with live instructor callouts and a final style exam.
Automated QA screenshots the title screen, each tutorial step, every enemy encounter and the final exam on the landscape layout, then the finished game is published with one click to a shareable link anyone can play on desktop or mobile.
