Hello runners,
We know people have been asking about this for a while, sorry it took so long... you can now enter Multiplayer with your Steam account, no sign-up required. Make sure you are updated to the most recent version (1.33) to use it.
For XGEN account users, you now have the choice to auto-login with the last username and password you used. Another feature that's been asked for quite often.
IMPORTANT - if you already use an XGEN account, don't use the steam auto-login - just log in the same way you always did before.
See you in the races!
