Maybe I'm being dumb here, but I've got the fortune pack (downloaded early in the game but not pre-start) but can't find the new weapons to buy at the gunshop - do I have to restart the game, or are these things just littered about, and if they are littered about does that mean you can't get the upgrades?? Are they only in the second map??? Can anyone provide a little clarification over the new weapons as a silenced shotgun sounds rather cool!!!

They should be inside a crate in your Armory, where you pick up guns. You don't have to buy them.
