Now I did a quick search, and only seen one guy. But he was wanting...pm blah blah.. Well no pm here and I don't care about thanks. I didn't come up with this, and no I didn't get it from that other guy either. A friend told me about this, and I'm sure a lot of you probably already know.
Go into a game. Frag yourself, go to pick up the weapon you just dropped from dieing. Throw a frag down, and then spam pick up weapon. Don't even try timing it just spam it.
*crosses fingers* Hopefully a patch will be out soon to fix this. Its as annoying as it is fun.
