22 levels were submitted to the 200 Brush Map Contest, held by planetquake.de. To be honest the quality of the maps is disappointing. The exceptions to this are Lunar Eclipse by [Tymo], Race into Space by mIKE, Electric Funeral by oly|Azrael and Dangeroids by Dangerzone. The only other map worth noting was a single player level called Last Resort chaOs. These levels are by far the best of the pack but game play tends to be very restricted and repetitive.
200 brushes doesn't seem so restrictive with Q3A that you couldn't expect better maps than these.
