BXR

MeleeFire: B,X,R or B,Y,Y,R As soon as your melee has hit your opponent and the damage is done, you can cancel the rest of the animation with X and open fire again. If done optimal it will seem like a melee and shot at the same time. To be done with a full clip or using Y,Y instead of X when not. Strangely enough, you will automatically get a full clip some time after a BXR, even if you shoot. Also works with sniper, but preferably press X before the melee hits so you are still moving towards your opponent and can get a clean snipe. Note - When you don't have ammo to reload your battle rifle, you can keep doing B,X,R
