ATC (Advanced Tactical Center) is a program the lets players develop tactics and strategies for Battlefield 2. You can draw-up some tactics on your own offline, or start an ATC server, have your friends connect, and then all draw on the same map. You can use it to design and document anything from a big opening move for a scrim to squad-level plans on defending a flag (see examples below)

You'll first need to download the main application, ATC Complete, which you can do for free from Foolish Entertainment. This will support Vanilla and all the official booster and expansion content.

To add support for all PoE2 maps, you'll need to download this map pack: ATC_maps_PoE2_v2.5.zip (88MB)

TO INSTALL THE POE2 PACK:

1. Unzip this zip file into your ATC install directory, by
default: ~Program Files\Foolish Entertainment\ATC for Battlefield 2\

2. It may 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 you're own [non-PoE2] 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 the pictures from 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 custom.xml file.
