Monster Games will release their dirt track at Charlotte on Friday, November 20, for Xbox One, PlayStation 4 and Steam. The track will be available for all series and modes.
UPDATE: (11-20) Dirt track at Charlotte has arrived for Xbox One, PlayStation 4 and Steam for $4.99.
RED4424 has posted a video preview of the track on his YouTube channel.
Just in case you missed it, the Dirt Track at Las Vegas was released recently, for $4.99. So it would seem likely that Charlotte would cost the same.
