Hex Cheat for Panzer General 2 


  This was used in the Blitzkreig Campaign. In the first scenario of the campaign save the game before
  doing anything. You should have about 500 prestige points. Exit the game. Using a Hex Editor open
  your save game and go file 00002D80. It should look like this beside it
  0100 0000 0000 0000 0000 0200 F401 1400.
  The offset F401 is the 500 prestige points. Change F401 to DAD6 to get 55000 prestige points.
  I dont know if the file where the prestige is will change in the other scenarios in the campaign as I just
  started playing.
  You can change it to more or less prestige points
  but I use DAD6 for a start.
