Here is a solution to cheat in Officers World War II
First make a shortcut with the Officers.exe then add -devmode
In Game open the console with ^ tilde key (left of number 1), here u can look at a list of all commands with
"help a-z" for exampel "help p" to use the command dont press ENTER press Tab!
if u want to add more tanks or inf just load the map u want and use the console command "Editor 1" and this time press Enter!
then the map will be loaded in the Editor and u can add any tank u want
save the lua and the xml file and enter quit in the console
then reload the map in the game and u can beat the Germans the way u want.
Have Fun!
