UMP

I know there is a hack to unlock the ump which is a Damn fine gun, but how do you get it by legit means. I have searched the rewards chart all the way to general of the army but there is no mention of it...

I'm pretty sure you can get it through a crate if you get lucky.

the very FIRST PAGE, you know that page you hit "new thread" on...
yeah.
its posted RIGHT THERE
why dont you READ SOME?

edit:
noi thats a lie made by cheaters

edit2:
if you mean without any form of glitches whatsoever - theres no possible way. hence why the gun is blacked out.
its a teaser, meaning it will be released later on in a patch for you to buy.
