Well, pretty obvious we won't be getting DLC for PSP now, however, the weapons seem to have found a way in anyway! Sodandy found a Bouquet in the demo off of De Ragan, a weapon from a previous downloadable mission, and I just found a pair of Sacred Dusters from one of the story missions in some boxes. (4th one, I believe. In the ice caves) Usually only obtainable from the Title or Unrecorded Order, a DLC mission as well.
What have you guys found in normal missions that's a new drop?
