Unzip/Unrar trainer into your game directory, then start trainer with "pdw3ftht.exe", and finally start the game. During gameplay toggle trainer options by pressing the following key combinations:
- Max. Gold
- Max. Wood
- Max. Food
- Max. Amount of gold in gold mines
- Max. Hero's Experience Points
NOTE: All of the options are based on mouse routine to ensure the computer doesn't benefit from them as well. So in order to get the options to work you have to move the mouse over the appropriate items first. Move mouse over Gold / Wood / Food at the top right of the screen to max it out. Move mouse over Gold Mines to increase its gold. Unselect and reselect heroes to give them full experience points.
Also note that changes will not be seen immediately, you have to buy something / let the heroes fight / etc to see values change. And finally, Food Option sets food to 0/100 as you can build as many men as you like.
