Ratchet & Clank: Up Your Arsenal Tips

Charge Boot Stop
Sometimes when you are chargebooting, you fly right off a clif and kill yourself. I found a way to stop right in the middle of chargebooting.

Start charge booting, and when you want to stop, press CIRCLE to fire any weapon you have. (anything that doesn't use ammo recomended)
You should skid to a stop.
