you need 2 people, i suggest making a room in russia or somewhere people dont go. Make sure both of you are in a room. Ok now this is all about timing so get it right. Now YOU leave and make another room, before that tell your friend to count to 5 and then leave the room you where previously in. By the time your friend counts to 5, you should of already made the room. When your friend joins the room, leave and come back and you should have all the guns there. You have a 20 sec time limit or else you will freeze.

Rep +1 if i helped :D
