Free browser multiplayer racing
Online Racing — 8 Pilots, One Stage
Ghost-style simultaneous time trial: everyone launches the same stage at the same moment, opponents appear as name-tagged ghost rovers beside you, and the server ranks the finish times. One shared link is all it takes to get your friends on the start line.

How a race works
Create or join
Host a private room and share the invite link, or browse the public lobby and jump into an open race. Rooms hold up to 8 pilots.
Ready up
The host picks the stage. Everyone readies up, the countdown syncs across every browser, and all pilots launch together.
Race live
Rivals render as live tinted ghosts with name tags — close enough to feel the pressure, immune to collisions. First across the line takes the room.
Why ghost-style multiplayer?
Traditional collision-based netcode punishes exactly the people browser games serve best: players on laptops, school networks, and phones. Mars Rally Championship runs your physics entirely locally — deterministic, full-fidelity — and streams everyone else's position as ghosts. The result is racing that feels simultaneous and fair on any connection: nobody can ram you off the ridge, and nobody with 300 ms of latency is driving a slideshow.
Multiplayer FAQ
How do I race with friends?
Open the game, choose ONLINE RACING, create a private room, and copy the invite link. Anyone who opens that link lands directly in your room — no account, no install.
How many players can race at once?
Up to 8 pilots per room, all driving the same stage at the same time.
Is it laggy? Do cars collide?
Opponents render as live ghost cars — you see exactly where everyone is, but there are no car-to-car collisions, so a laggy connection can never wreck your run. Your own physics always run locally at full fidelity.
What happens if someone disconnects mid-race?
They are marked DNF and everyone else races on. Your own run continues as a normal solo run, and finish times on championship stages still count for the global leaderboard.
