SCS Software's trucking simulators have had robust from modders for ages, including a massively-multiplayer online mode with TruckersMP. Official multiplayer came to Euro Truck Simulator 2 earlier this year, and while that implementation is quite different than the one modders built, it offers its own key advantages. Soon, those advantages will include for even more mods.
Mod for the Convoy multiplayer mode will go live in patch 1.42 for both ETS2 and ATS, and it's already available for testing in an open beta. As of this update, the server browser will now show you which – if any – mods are required for a given session. If they're available from the Steam Workshop, you'll be able to them directly via an overlay without even needing to exit the game.
"We expect a majority of popular modifications to work from the get-go with this update, however, there may be some compatibility issues with others," the devs say in the announcement. There are some minor caveats, too – many sound mods will only play for local s, for example, so you won't be able to impress your friends with your custom truck horns.
The devs previously teased both mod and bigger player counts coming to Convoy "eventually", so it's good to see parts of that effort being fulfilled sooner rather than later.
