Things You'll Need
Instructions
Start playing a game.
While playing, access the game's control scheme and bind the mouse wheel to your crouch button. To do this, select "crouch" with your mouse, then scroll down on your mouse wheel. Make sure that both your mouse wheel and the "Ctrl" button allow you to crouch.
Leave the menu and scroll down on your mouse wheel. Your character should now be ducking rapidly.
While doing this, press the "Ctrl" button every two seconds. This should cause your character to jump/slide forward. You are now silent running.
