Ok so this my first post in 190 day woot woot ....ok to it then,
this is a very simple a easy glitch to do at anytime anywere with a vendor so,
BACKPACK GLITCH: 20 More Spaces
1. Sell 20 or less items and no more than 20 to any vendor
2. Fill backpack to max capacity
3. Buy back items
voila you have a overfilled backpack yay
VAULT GLITCH: Unlimited space
1. Go to vault with overfilled backpack
2. Pick any weapon among your vault items to swap
3. Go over to backpack side and choose what you want to vault
4. Items wont swap out but will take any extra item you choose to vault till you have regular backpack space
voila you have a unlimited spaces
EDIT:Ok some ppl seem to have problems with this ok the backpack glitch it not really something you just run around with its mainly used to store in vault but it helpful if you just want to carry your best weapons with you and after you fill you vault up and if you still want to store weapon but cant and want a empty backpack just do backpack glich but fill the extra 20 with crap weapons and store good in vault then sell crap weapons so you can still pick up stuff and if you haven't figured out how to look at all your weapons tap right trigger then tap left trigger voila you can now navigate the vault and backpack note vualt might take 3 taps of left or right
please don't get mad if this is a already discovered glitch im not trying to take credit for it but if its not posted yet then i do :) i couldn't find it and thought this would be helpful and it would be nice to get my first thanks so plez appreciate this
Ok so here it is took me a while but i did it Lvl 50 Assassin, Vault has tons of weapons and alot of duplicates sry about that but mostly all different and tons of skins and heads and 1 new skin i just picked up from the vendor
