This are Point of Existence Advanced Tactical Center Maps.
If you don't have "Advanced Tactical Center for BF2", you can grab
it here: Foolishentertainment.com (64MB)
TO INSTALL:
1. Unzip the zip file into your ATC install directory, by
default: C:\Program Files\Foolish Entertainment\ATC for Battlefield 2\
2. It should ask if it's ok to overwrite files - say yes. The maps
should land in ~\ATC for Battlefield 2\Pictures\Custom\ and the
custom.xml file should go in ~\ATC for Battlefield 2\Data.
NOTE:
If you currently have custom maps in ATC, this zip file will overwrite
the xml file causing your previoius custom ATC maps to be invisible in
ATC - though it doesnt delete them. You can fix this issue by simply
re-creating your custom maps once the PoE2 maps are installed.
Alternatively, you can copy the contents of the enclosed custom.xml and
then paste them at the end of your current custom.xml file.
