Build four games in parallel with agents
Four Grok 4.20 agents built a tower defense, mini Factorio, CHIP-8 emulator and roguelike shooter in parallel over a day.
- What They Did
- The user directed Grok 4.20 at game development tasks. Its four agents split each problem on every prompt, built components in parallel, and merged the outputs. This produced a tower defense game, a mini Factorio, a CHIP-8 emulator, and a roguelike shooter.
- How It Went
- All four games were completed in one day. The emulator correctly implemented the full opcode set on the first pass.
- Worth Knowing
- The entire effort took a full day.
