Note: This procedure requires editing a game file; creating a backup copy of the file before proceeding is recommended. With a text editor, edit the .CFG file that corresponds to your current saved game in the "\data\save" directory in the game's folder. Locate the "@game_difficulty =" line and change its value from 0 to 3. "0" is the easy difficulty, "1" is medium, "2" is hard, and "3" is extreme.
