About Mind Prison: The Last War
A lite 4X strategy game with a retro terminal look. You play a war AI that reboots after 800 years of silence and conquers sectors one by one, deciding whether to occupy, raze, purge or assimilate each world you take while a rival AI faction runs its own economy. In its AI content disclosure on Steam, the developer says the game is "Vibe Coded" and that its images are AI-generated, while the UI, story, voice lines and sound effects were made by hand. No AI tool is named. It is sold on Steam for Windows.

“Vibe Coded 4x Lite Strategy Game, With Ai Generated images. But hand made UI, Story & Voicelines and Sound Effects”Verification notes: Release date, US price, platform, developer, publisher and languages checked on the Steam store API; the "Vibe Coded" wording comes from the developer's AI Generated Content Disclosure on the Steam store page. No AI tool is named. An unverified report of a developer comment on r/aigamedev about building it in two days with AI agents could not be opened, so it is not used.
