then what you do is you go in either one and open the mystery box and then go to perk machine and wait till you gun shows up and then you get the perk and you run to the mystery box and while your still drinking the perk go get you gun and there you go . you did the glitch . if it doesnt work you did something in the sequence .
yup and if you time it right you should have 3 guns (but just it case have you bad gun out) until you get good at doing it)
