I've found two weapons so far that have some red text in the properties box. One was a revolver that said "I am free now". Another was a sniper rifle that said "I can see my house from here." I believe I got them both as bonus rewards for the assassin quest in Southpaw Steam and Power. I assume they won't be the only weapons in the game with properties that are in red text, though.
Do these properties actually do anything like give hidden bonuses to the weapon, or are they essentially just some flavor text?
