Borderlands 3 Inventory Slots
At the start of Borderlands 3, your Vault Hunter has 2 weapon slots, a shield slot, and a slot for a grenade mod. Throughout the tutorial, you will find gear to fill up those inventory slots and create a nice loadout. However, there are more slots that you can unlock throughout the game. There are 2 more weapons slots, a slot for your class mod, and a slot for an artifact that you can unlock. Depending on your playstyle this can take a while to unlock them all. Because these additional loadout slots will become available by completing certain story missions. So if you are a completionist and do all the side-missions and crew challenges it can take a while to get access to all the inventory slots.
