You’ll start off with seriously limited storage space in Borderlands 3, and that includes the ammo you can carry for each type. You’ll likely outgrow this pretty quickly however, and will want to invest on making some upgrades. In this Borderlands 3 SDU Guide, we’ll explain what Storage Deck Upgrades are and where to get them. We’ll take a look at when you’ll unlock the ability to upgrade your storage space in Borderlands 3, and how much it’ll cost you.
How to Increase Storage Space
When you start off, you’ll find yourself constantly running out of ammo, and maxing out your inventory space. This is alleviated once SDUs are introduced. Storage Deck Upgrades can be purchased to boost specific areas of your inventory, though it’ll get pretty pricey as you unlock more of them.
Where to Buy Storage Deck Upgrades (SDUs)
So you know that SDUs increase your inventory space in Borderlands 3, but where do you get them? Well, you’ll need to make it to Sanctuary, roughly 3 hours into the game. This is your hub aboard a star ship, and you’ll have access to Marcus’ Munitions. From here you can purchase Storage Deck Upgrades and increase the amount of ammo and loot you can carry.
You’ll need to purchase SDUs to increase your inventory in Borderlands 3, with each ammo type requiring its own upgrade. Here are the options:
- Pistol ammo
- Heavy ammo
- SMG ammo
- Assault Rifle ammo
- Grenade ammo
- Bag storage
- Bank storage
- Lost Loot storage
- Shotgun ammo
- Sniper Ammo
There are 8 upgrades available for each SDU type. These will increase in price the more you buy, with the first few prices being 1,000, 3,000 and 9,000. Some upgrades like the bag SDU can reach prices as high as 81,000 as you upgrade, though it’s worth it for the extra loot space.
