A backpack, or an improvised backpack (as it is named in the game), is one of the most important early-game items in the game. You’ll need it to store more crafting materials, ammo, edible goods, and so on. To make your first backpack, you need three crafting materials: wooden sticks, rope, and a burlap sack. You can harvest sticks and rope from bushes or find them in various warehouses, supermarkets, and other residential and commercial areas in the game. You can also craft sticks from larger pieces of wood. To find a burlap sack, you should explore sheds and warehouses, as well as industrial areas. Although rope is a naturally occurring item in the game, you can also craft it from rags or guts. The crafting process is as follows, on all platforms: 1. Drag the burlap sack from your inventory and put it on the ground. 2. Take the rope from your bag and drag it over the burlap sack. 3. From the actions list, select to craft the improvised courier bag. 4. Leave the bag on the ground. 5. Drag your wooden sticks over the courier bag and choose the recipe for the improvised backpack. 6. Take the backpack and equip it to get extra inventory slots and storage space. Note that you can also make a leather improvised backpack. The crafting process is identical with one small exception – instead of a burlap sack, you need a wild boar pelt. Go hunting and replace the sack with the pelt in the previous recipe. A leather backpack gives you five additional inventory slots from the standard 20 slots of the regular backpack.
