I no how you feel, I can only get to 16 as the team i get are terrible. Theres nothing on youtube, but apperintly if you go to 1 of the rooms with the random box in and a perk machine and random it then run get your perk as ur drinking it run and grab yout guna you can get 3 guns but havent tried myself could any one say if it works,

The map has only been out for about 15 hours so how can you say "they never do". Give them some time, the people that find the glitches stay in them so they can get high on the leaderboards and then once they are done then they take their time to make a video. Remember people are doing this to help you, they dont "need" to be posting anything but if they do just give them some time.
