Note: this changes a critical game file. Make a back-up or you may mistakenly alter your NTSF or FAT.

Locate the MainINIFile.ini file in the ...\Program Files\PopTop Software\Shattered Union\Data\Other directory. Change the file attribute from Read-Only and open it using a text editor such as Notepad.exe. Search for the string:

- "INT SellPercentageOfPurchaseCost=75"

and change the value to 1000 (or anything over 100). Save the file and boot the game. When starting a new campaign, immediately sell all your units and you will receive the amount of money equal to the percentage you entered.
