Some of you might already know this, but for those who don't know. You can actullay use the JO kicks in JA SP too. (Havent tried it in MP yet.)
Its the same, aim your crosshair at someone, run towards them and tap jump twice. (Its best to aim for the legs) And it works when you're using dual sabers, staff and single bladed saber.
Side-kicking is also the same. Just tap strafe left/right and tap jump.
And the JO kicks does more damage than the normal kicks when you use the saberstaff!
