Before moving the files, make sure you back up the original maps (map1, map2, through 14.) in a seperate folder in case you want to revert back to the original maps.

Copy the maps into the map folder (should be C:\Program Files\Lugaru\Data\Maps on a Windows computer, IDK about Mac or Linux). It will probably prompt you if you want to replace the files. Select "yes". Open Lugaru normally. The challenge maps will now be replaced with my maps.

If you screw up and lose the original maps, they're backed up in the "original maps" folder for your convinience.

Next step: Play them all and tell me what you think on Wolfire.com!!!

...Or else.
