About Mars Rally Championship
A full 3D rally racing game that runs entirely in your browser — no install, no account, no paywall. Rally stages on real Martian terrain, online multiplayer, a global leaderboard, and a physics simulation honest enough to replay bit-for-bit.
Why the browser?
Because the start line should be one click away. Mars Rally Championship loads like a website and drives like a sim: WebGL rendering with real-time post-processing, a per-wheel tire model running at fixed substeps, dynamic resolution scaling that adapts to your hardware, and touch, keyboard, and gamepad support. Phones, laptops, school computers — if it runs a modern browser, it runs the championship.
The simulation-first bet
The game's core decision is determinism. Terrain noise is seeded, physics steps are fixed, and every input is recorded — which makes each run perfectly reproducible. That single property powers the features that matter: bit-exact ghost replays, downloadable rivals from the global leaderboard, a rival ladder that always gives you a beatable target, and lag-proof online multiplayer.
A living game
Beyond the Mars Cup there's a daily challenge with streaks and quests, a garage of earnable cosmetics, two dozen achievements, dust storms that change your stage mid-run, a voice co-driver calling pace notes, and the level editor that built the championship's own stages.
Made for pilots, not accounts
There is nothing to sign up for. Personal bests live in your browser; submitting to the global leaderboard takes a call sign, not an email. The game is free and stays free.
