I'm not very good in building duke's map but here there are some of mine.
As you will see I like huge space maps; thats because it's much fun to play by bike.
The testtour.map it's a test map that Iused to calibrate my VIRTUALBIKE and to learn how make very very big map...take a look at it. Using two or more virtualbike could take half an hour or more to catch the oher players...

TESTTOUR MAP

COMETA MAP (this is really the very very first cometa.map made to test our first dukeonbike device...but we are still waiting from dukeworld.com the permission to put on the net the other files)
