Cars
One of you drives. The other rides along, plays with the radio and comments. Lights, wipers and fuel match for both. If you crash, you crash together.
My Summer Car multiplayer
The whole village,for your crew
Your friend rides shotgun and watches you forget to tighten the wheels for the third time. Up to eight people in a lobby, and the world is shared: jobs, the shop, the sauna, police and rally.
8people in one lobby, a slider from two to eight
225scenarios we test automatically inside the game
11areas of the game, from Peräjärvi to the rally
What the mod does
You can do almost everything together
We went through the game chain by chain: who does what, what your friend sees, and what happens if you both grab the same part.

What is already tested
Every mechanic runs through an automated test inside the game: one player is real, the other is a program speaking the same network protocol.

FAQ
If something is unclear
Your question is not here? Write to us and we will sort it out.
Write to supportDoes every player in the lobby need a licence?
Yes. A licence belongs to one Steam account, so each player needs one — whether there are two of you or eight. Plus their own copy of My Summer Car on Steam.
Where is progress saved?
With the host, in the regular game saves. The guest’s wallet and items are written to the host’s save too.
Do I need to open ports or use a VPN?
No. You connect through Steam, like any game with lobbies.
Does the mod change game files?
No. The launcher starts the game through Steam and loads the mod in memory. Game files and saves are left alone.
Can I get a refund?
Yes, if you have never joined a co-op game with the mod. Write to support and we refund the full amount.
Is this an official mod?
No. We make Kimppa; the developer and publisher of My Summer Car have nothing to do with it.
