So, I beat Splinter Cell: Conviction but how do I......?

...unlock all the rest of the guns?? I have all of them except the machine pistol, (not the scorpion, the other one), the ak-47 and the other ak rifle. How do I unlock these? Please tell me if you know how!!!

some guns can only be unlocked in co-op story, i know for a fact that the AK-47 is one of those

really? that sucks! I know you can get them in Deniable Ops but I tried and it didn't work

yea the guns only unlock in story and co-op story, you can pick them up in the deniable ops but they wont be saved in your weapons.
