We have added instructions for 'flipping' scenarios (e.g. allowing the player to play the "opposing forces" in an existing scenario). You can find the tutorial page here:
http://www.prosimco.com/atf/tutorial/38_flip.htm
These instructions are designed for ATF version 1.05 and Raging Tiger 1.14. Do not attempt to use them until you download the
official upgrade (which should be released next week).
