I've uploaded a new version. Here are the changes since version 2, which is the one currently available for download.
Version 4:
* Rearanged the spawn points
* Added multiple new waves for brutal
* Changed several waves to make the map more challanging
Version 3:
* Improved hunting scripts
* Added new version of wave 2 for hard
* Changed spawn point of airstrikes to provide a longer period to
respond to the warning
* Moved wave 8 hard to wave 8 normal, and added a new hard wave
* Made minor changes to some other waves
* Moved the lower left spawnpoints a little to make the unit
appearance more realistic
* Gave each player a buggy with full experience and extra armor
* Added tips to the readme file
So basically the map is now better balanced, offers a wider range is challenge from easy to brutal, and is simply more fun to play :)
Enjoy!
