I have teased Helios already in the beginning of this year, and now is the time. It is in public beta, still working on the site though.
You can find the game launcher here: https://helios.jvar.nl/ After you have downloaded the launcher it will automatically download and unpack the client you need to start gaming.
When creating a user prefix it with "new/" to create a new user, after this you can start racing :D
Keep you posted with new updates.
