Ratchet & Clank: Up Your Arsenal Cheats

These cheat really only works in Lock-Strafe.

To do a multi-shot, get out any weapon that takes a while to refire. (this will not work with a N60 storm, mine glove, or Lava gun)
Press R2 to go into first person mode. Press Square and then R1 very quickly. If done correctly, your wrench should not have been thrown, and your gun will be out. On other peoples screens, they will see you holding a wrench. You must keep the R1 button held down to make it work. When you are ready to fire a multi-shot, press the Circle button (the other fire button) On your screen, nothing will happen except you will fire again. on other screens, you will fire as many shots as you fired when you were walking around holding R1.
