i tried it once it said i unlocked the acog for the guns and i got 5000 xp but it did not really give me the xp and my guns did go to 149, i tried it my turning my switch off on my wireless router then i tried it by turning my ps3 off, when i turned the ps3 off it did nothing at all but turning the router of it did what i said above, still not sure but dont think it works, if it does we need more info.
