Free multiplayer car-combat game in the browser: wreck rivals, drift the open city, duel AI rivals — no download
Wreck Valley is a free multiplayer car-combat game that runs right in the browser — no download, no ads. Drive into an open city, hunt rivals, drift through chaos, with modes for real-player multiplayer (up to 100 players), seven AI rivals to sharpen against, a 1v1 duel against the "Jev" AI, and a garage to customize your ride. Mobile touch controls and private rooms included.
It launched in early October 2026 and the live servers are running now. The development story is the VibeFix part: the author built it with Claude Code (Opus 5.5) and Astra, and used AI the way a studio would use a QA and tuning team — playtester bug reports were turned into fixes with before-and-after numbers, AI rivals were trained via self-play, and the live server was load-tested with 20 bots across five regions while the author played.
A full 3D multiplayer combat game, shipped to production with AI as co-developer, QA lead and sparring partner.
