Blog Andrew Joseph 29 Oct , 2025 0
Are you confused because you can't seem to unlock more weapon slots? The Outer World 2? Mind you, this isn't just weapons. The types of grenades and medical inhalers you can equip at any given time also tend to be very limited.
How to Unlock More Equipment Slots in The Outer Worlds 2
There are several ways to unlock additional inventory slots in the game:
- One option is to use socket mods that grant additional sockets. Note that this effect will remain in effect as long as you have the gear equipped.
- Another option is to choose the right benefits. Please note that this effect is permanent.
Armor mods that provide bonus equipment slots
If you want to unlock more weapon slots in The Outer Worlds 2, as well as grenade and inhaler slots, then you can choose to find the following mods:
- Extra Holster – Gain extra weapon slots.
- Grenade Clip – Gain an additional grenade slot.
- Extra Primer Ports – Get extra slots for medical inhalers.
These items are usually sold by vendors in settlements. Alternatively, you can loot them from certain enemies or containers.

How to apply armor mods
Once you have the mod, you can attach it to a valid helmet/headgear by interacting with the workbench. Select the “Mods” menu and select the option you want to connect to the helmet. Some things to keep in mind:
- Any mods you have attached to an item cannot be removed. Any new mod you apply will break the previous mod.
- If you switch to a different helmet without the necessary mods, you will lose the effects and extra slots.
