Im happy to say that there are now two more maps available for download.
Guts Deathrace by Gutrench, a sky challenge track that tests your speed and skill to win the the flag or plummet to an early grave.
2005 by DTM Racer and ISR KSO, a racing and fun map with no flag to cap. The track is a mix of what looks like dockyards and urban city with several routes that splits and then rejoin to take you back to the start.
As you may know there has been a site setup to develop a new expanded version of interstate, I will be keeping an eye on the progress, and look forward to seeing its development Give them a visit at http://is82exp.bf1942files.com/
