How it was made: according to the developer's AI disclosure on Steam, the game's 3D models, props and characters were built with Blender Python scripts written by the AI coding assistants Claude and Codex, and the game code was also written with AI help. Stable Audio Open Small, Stability AI's small audio model, generated some sound effects, including layers of the hammer impacts and explosions. ACE-Step 1.5 generated the five neighbor-wall music tracks. The developer says it picked and edited all of that audio, and that the rest of the sound is synthesized in code or taken from CC0 sample packs. The disclosure says the game has no AI voices and no AI-generated images or textures, nothing is generated while you play, and the store page text was drafted with AI and reviewed by the developer.
In its first Steam devlog, the team says it drew on how common disputes over upstairs noise are in Korean apartment buildings, and that it used automated bot runs to measure changes to late-game pacing. The launch version adds a Floor Echo mode and a short Contract Demolition mode, and the text is in 10 languages. BIGGER BANG costs $3.99, with a 15% launch discount for the first two weeks. Details here come from the developer's Steam page and posts.
