On the sniper, Bolt Action, and Run & Gun Rifles you can adjust the zoom speed, zoom distance and the scope. To do this you will need to go to the download section and download the riles you want to adjust from the -=CoN=- Server Mutators section.
Each of the zip files has an .int file in it for the rifle (For our example we will use the sniper rifle). Place that int file in the system folder of your unreal tournament. Then start the game. Once you are at the menu screen, go to the Mod drop down section and select the rifle you want to adjust.
This will open the option screen and you can adjust the rifle to your preferences.
Once set you can click close.
This will need to be done for each rifle you want adjusted.
