A backpack is an item that allows you to increase the space available in your inventory. If you have this item, the number of inventory slots expands automatically by the number of slots available to all characters in their backpacks.
The items placed in the backpack are displayed in the lower left part of the inventory window.
Each playable character can be equipped with a separate backpack. In this case, the number of available slots in the inventory is summed up! The contents of all backpacks are available in the inventory as the player's property.
Items from the backpack slots are lost upon evacuation.
Backpacks with a different number of slots can be purchased from the in-game store.
