If you are running Vista in Classic mode, find the following exe file:
"C:\Program Files (x86)\Activision\Wolfenstein\SP\Wolf2.exe"
Right-click and create a desktop shortcut.
Right-click on your newly created desktop icon and select properties.
To the end of the Target line add +set com_allowconsole 1 and click apply.
The Target line within the shortcut should now read:
"C:\Program Files (x86)\Activision\Wolfenstein\SP\Wolf2.exe" +set com_allowconsole 1
Run the game.
When in game ie game loaded and running, press Right ALT + Left ALT + ~ ( here, the key directly below ESC) to show the console then type the following codes for the desired effect:
giveallintel: All Intel
givepowers: Give All Veil Powers
giveallpowerupgrades: Gives All Power Upgrades
givegold: Gives desired amount of money
god: God Mode
notarget: Ignored by enemies
momoney: Sets total Money to $31,337
giveachievements: Unlocks Achievements
giveobjectives: Unlocks Objectives
This does work :-)
