In the December 18, 2023 update, as was warned in its patch notes[hotwheelsunleashed.com], Milestone added Epic Online Services (EOS) to the game in order to add functionality for cross-platform friends parties. But what if you have zero need of that (like me, who's a lone wolf player)? Good news: You can disable EOS from the game, and cross-platform multiplayer will still function without issues as it did during the game's launch period!

As a preamble, if EOS was already installed by the game (or any other game), uninstall it first using your means of choice. (Mine is Revo Uninstaller[www.revouninstaller.com].)

Browse to the game's local files and:
-in hotwheels2.ini, change the line NoOperation=0 to NoOperation=1
-in the "Installers" folder, rename the following files:
to something else, like this for example:

That's it!
