Kaiju Rampage is a comic city-destruction arcade game built by Neta Studio AI from a single sentence. Pick your beast. Flatten the city. You control one of four barnyard kaiju — Cockzilla the rooster titan, Turbo Turkey the speed demon, Shell Shock the armored tank or Mad Pork the rage brawler — as you climb skyscrapers, punch through walls, and smash every city block to rubble while cops, snipers, tanks and helicopters scramble to stop you.
The game packs cel-shaded cartoon kaiju art, speech-bubble dialog from helpless victims and cops, subtitled character banter, a survival-heat escalation system and a boss robot fight every fifth level. It runs directly in the browser — no install, no download.

Game Features
- Live LLM Narrative — every victim scream, cop taunt and character subtitle is improvised live by a language model; the dialog bubbles change on every run, so no two rampages read the same (deepseek-chat live narrative).
- Four Playable Kaiju — Cockzilla, Turbo Turkey, Shell Shock and Mad Pork each have unique stats, signature moves (Peck Fury, Dawn Roar, and more) and their own profile portrait in the HUD.
- Fully Destructible City — climb any building, ride up and down its sides, punch through walls, floors and roofs, and flatten every block; each structure has its own health bar and three damage states (intact, damaged, rubble).
- Survival Heat System — the more you smash, the hotter the response: panicked civilians and cops at first, then firefighters, military tanks and attack helicopters as the heat rises — with anti-air special moves to blast them down.
- Boss Battles Every 5th Level — a giant hostile military combat robot with missile launchers on its shoulders and a glowing red visor awaits at the end of every boss level.
- Instant Browser Play — runs directly in your browser with no download needed; play with arrow keys / WASD on desktop or the on-screen D-pad and SMASH buttons on mobile, and share your run instantly.
