Cheat: Resources
Most of the cheats for Hearts of Iron 2 are the same as the first one. Hit f12 and type in the name of the resource to get 5k more of it.

Cheat: Quick Units for Free
Note: When editing game files always make a back-up. First, go to your program files, then the Hearts of Iron II or paradox Inter. folder. Then go to the folder titled db, then the units folder, the brigade or division folder. In either one pick the units you want to change. All you have to change is the cost and build time to either 1 or 0. Changing anything else will cause the game to crash.

Hack - Resource and Manpower
Get loads of resources and manpower Back up the file you are going to alter, or you get a free game-screwing!

Go to the directory /HOI2/db/events and in there you should find many text documents. Locate the one file called RandomEvents and open it using Notepad or similar text editor (note you need to save the file with the existing extension). Search the bottom of the file and just add:

}
