How to change campaign map?

[Nighthawk117 1]

How do I make it so that the default campaigns in SF2 use this map 

 Instead of the stock desert map?

Go to your campaign.ini file and right at the start you will see this :

[CampaignData]
CampaignName=590901 Operation Burning Sands
DataFile=Campaign1_data.ini
CampaignMap=DESERT4     ------- change this line to DESERT4 and this map will now be taken instead of the default desert one
Historical=FALSE
Service001=USAF
Service002=USN
Service003=USMC
Service004=Merc

It's not really that straightforward as 1977Frenchie says, though. The Desert4 terrain contains additional target areas and alters some names of original target areas, IIRC. To have a properly working campaign, target area names referenced inside the campaign's _data.ini file must be changed as well, and it's a time consuming job. Luckily there's a mod updating all Desert campaigns to be used with the Desert4 terrain, here at this link: 

PS: the above mod also requires the user to install an additional terrain update by Centurion1, which alters the names of airbases. All the required stuff is linked in the mod's page.
