Borderlands 2: How to Increase Inventory Space
If you’re a hoarder like I am, then your primary goal in Borderlands is to carry around as much crap as possible in your backpack.
I can’t lie, I carry way too many weapons with me at all times, but what can I say.. I like to be prepared.
Luckily, you can upgrade your inventory size by purchasing backpack upgrades in the Black Market.
You’ll find the Black Market on the southeastern side of Sanctuary, outside of Moxxi’s place.
The backpack upgrade is called a Backpack SDU, and it’s always in the right hand slot in the Black Market.
The backpack upgrade costs 4 Eridium, and increases by 4 Eridium every time, but how can you put a price on inventory space?
Easy, you can’t.. it’s worth it, whatever the cost! Don’t judge me..
