Here are all of the leaked guns with some information and pictures. Note to mods: This is not the same thing as other threads this has pictures of all guns leaked not just text.
Update as of 5/31/12: Obviously most of the guns listed in this thread as we all know are going to be false and not in the game due to these are guns that were used around the 70's give or take maybe the 60's or maybe the 80's. But since we now all now know the game will be place in the future around one decade in the area of 2025 I have now updated and the guns below are guns that were spotted in the trailer which are confirmed in singleplayer at least and maybe multiplayer.
