This glich allows you to walk 1.5x faster with Leon. First equip the striker shotgun, and exit the menu. Hold R1 to pick up your weapon and then press the menu button before the laser on the gun is shown. Now you are in the menu because of pressing the menu button you can equip another gun. Now when you exit the menu, Leon will run 1.5x faster than normal. This glitch will stop working after opening doors when the black screen comes up, climbing ladders and selecting the stiker again.
