This savegame provided by StevenThrasher is an ultra-hard version of the Skirmish Trail map Desert Heat : Isolation. It existed in the game briefly between two patches (16. October to 06. November 2014). The first patch was made to stop winning this map by rushing, but it turned out to be extremely difficult and was therefor re-balanced in the second patch.
The story of this can be found here:
The thread also provides guidelines on how the map can be survived through the early phases.
It is an ultra hard version of this mission for an expert player who is looking for a real challange.
Thanks go to StevenThrasher for going back into the battle to provide the tips and help with this mission along with the earliest savegame.
Enjoy the map and ..... Good Luck
