I've had an e-mail from the BETA team at EA Motor-City Online that they have opened their BETA testing for the game.
I'd personnally not actually heard about this game before yesterday (sorry EA!), but apparantly there is quite a following for it already.
On closer inspection though, the BETA test is only open to citizens of the United States & Canada, and there is an administration charge of $5 (to be paid online).
If you want to sign up for the BETA test, or find out more information about Motor-City Online, you can visit the official web-site by clicking here. (Link opens in a new window).
