Backpack

Thanks to the backpack, you can store most of my weapons in one place. Additionally, it allows you to store any type of ammunition (except for minigun and rocket launcher ammunition) in quantities of up to 100 pieces of each type. Besides firearms, you can also store melee weapons and other items, thanks to several available slots. The backpack has a built-in battery where you can store energy or charge your lighter, minigun, or any other electric items that I may add in the future.

You can obtain this backpack from drops that appear every few days. When you open such a drop, there is a chance that one of the loot items will be the backpac

Here is the inventory right after opening the drop:

And here is the fully loaded inventory

As you can see, there is still some space on the sides for me to add new items in the future. Additionally, there is a crafting mat in the middle where you will be able to craft various items. However, currently, you cannot use it because I do not have any ideas for what items could be crafted on it.
