In Borderlands 4, the default two weapon slots quickly prove inadequate given the sheer volume of firearms available. Fortunately, expanding your arsenal is straightforward—progression through levels unlocks additional slots.

Expanding your loadout capacity

New weapon slots open at Levels 5 and 8, enabling greater combat flexibility. This allows customization of your armory without restrictions—carry four rocket launchers if desired. Post-unlock, focus shifts to Enhancement and Class Mod integrations, which significantly augment gear performance. Enhancements apply manufacturer-specific buffs, even to licensed components, making strategic weapon pairing essential.

Managing multiple weapons requires frequent gear evaluation and ammo monitoring. Duplicate weapon types deplete shared ammunition reserves faster—prioritize SDUs to expand capacity for favored armaments. Experiment with different loadouts to discover synergies that match your combat approach, then return to spread mayhem across the battlefield. Explore advanced tactics through dedicated game guides to maximize your destructive potential.
