Hi there, the site is indeed down at the moment, no idea why.
Try
this alternative link for the launcher meantime.
(If the download doesn't work, use a firefox browser)
This launcher is hosted on our Discord, and has been retired from the official site because it was detected as a false positive.
Since there's no page I can send for you, here are a bunch of things you should make note of:
- You and your friend should have the same mods & mutators enabled to play together
- Multiplayer is very experimental and a lot of bugs are to be experienced
- It has no missions
- It has no traffic & pedestrians
I hope this helps, let me know if you have any issues with that launcher!
