Where's the Masterkey UBS? It's not on the list. And you know why it's not on the list? Cause it's fucking good and no-one can question that statement.
Edit: If you question whether the UBS is good you are prolly the shitty runner I blasted into the dirt because you saw I had a M41 and thought, "LOL I can just get close and abuse close range combat mechanics for marines LOL." - Last thoughts of dead runner on the ground.
