A 32-year-old solo developer in New York built Aftershock Online, a single-player superhero MMO where your party and raid teams are AI heroes, entirely with Claude Opus 5.5 in six weeks across 18 versions — even the trailer was made by Claude.
- 68 powers, fusable into 4,719 builds; 99 quests, 5 dungeons, two 10-hero raids, world bosses, and a nemesis that remembers you
- The whole game is a single 3.5MB HTML file running in the browser; first 15 levels free, full game $5
- Cost: 3B tokens on a $120/month Max+Pro subscription, vs an estimated $2k–$9k at API prices
- The hardest part was balance: at one point his level-50 build hit 400k DPS and nothing could threaten him
