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 "player.ini", "player airplanes.ini" and "player guns.ini" files in the game folder. In the "player.ini" file, find all the "rof" (rate of fire) entries and change them from "3.5" to "35". In the "player airplanes.ini" file, change all of the health entries by adding a few of zeros. Reduce the health values for the enemy planes and enemy boats.
