Solo dev builds full MMORPG with Claude Code: custom tools, 23 invariant checks, alpha live
khyrichan · reddit · 2026-10-18
A French solo developer details how he's building Death Leaves a Trace, an isometric dark-fantasy MMORPG in Unity 6, entirely with Claude Code alongside his day job (400 hours since August; first closed alpha peaked at 8 concurrent players with zero crashes; Alpha #2 with 100 slots coming). Highlights: driving Blender via MCP to create assets and entire cities; three custom Windows tools (Workshop/Forge/Cartographer) wired to live game data for creatures, items and world-building; a custom launcher, deployment pipeline and server monitoring dashboard; automated tests plus 23 invariant checks and docs. His key lesson: regression safeguards matter as much as code generation.
