Here is a modification that will make the missions within GTA Vice City more difficult by lowering the weapons power, however this would also affect your enemies weapons also. This modification would basically be the same for those missions that are gun fights, and more difficult for those that include destroying targets such as a person or a vehicle. This is recommened for those that have completed the game a long time a go and want a new challenge.Please note that it is highly recommended that you back up any files just incase you do not like this modification or it messes up your game, so that you don't have to reinstall.
