Anthropic's Opus 5.5 generates complete retro mobile game

A user reported that Opus 5.5, an AI model, successfully generated a complete Duke Nukem 3D-style shooter game for older J2ME phones. The AI created a Java-based 3D engine with features like textured floors and fog, designed all game assets including characters and monsters, composed MIDI music, and produced voice lines. The entire game, packaged as a half-megabyte JAR file, reportedly worked immediately upon transfer to an old phone, rivaling the quality of commercial games from that era. AI
