Invincible units
Note: This procedure involves editing a game file; create a backup copy of the file before proceeding. Use an archival utility such as WinRAR to extract the files found in the "game.pak" file in the "\ubisoft\faces of war\resource" directory. Specifically, extract the "tactis.dl", "normal.dl", "hard.dl", and "easy.dl" files in the "set/difficulty" folder in the "game.pak" archive file. Use a text editor to edit the extracted files and change value under the "ally" header in each of the files to the following:
ally
health_increase 40
health 40
Add the modified files back to their original locations within the "game.pak" file with WinRAR or another archival utility.
