How to Get Backpack Extension in Once Human

Once Human is a challenging survival-crafting RPG where every resource counts. As you explore the post-apocalyptic world in search of resources, your inventory quickly becomes a limiting factor. If you have limited carrying capacity, you’ll find yourself struggling to gather essential items like Electronic Parts, Rare Crystal Sets, and ores, ultimately limiting your progress.

As such, increasing your backpack storage and overall carrying capacity can come in handy. By expanding your carrying capacity, you can gather more resources, explore further, and better equip yourself for the challenges ahead. This guide will show you how to quickly increase your carrying capacity in Once Human.

How to Increase Carry Capacity In Once Human

Like most survival games, Once Human gives you the ability to craft an upgraded backpack that can significantly increase your storage capacity. To do so, you need to unlock the Backpack Expansion Memetic Specialization which pops up once you reach level 15.

Since Memetic Specializations in Once Human depend on RNG, you may not get this particular expansion at level 15. If it does not show up, continue to level up until you can unlock it.

After you’ve unlocked the Specialization, head to an Intermediate Supplies Workbench and craft the Backpack Expansion using:

15x Rubber.
10x Metal Scrap.
10x Rawhide.

Once crafted, equip the Backpack Expansion from your inventory. This will immediately increase your carrying capacity by 40 kg.

Alternatively, you can put on weight and bulk up your meta to increase your carrying capacity. Overweight characters can carry more loot and resources and deal more melee damage. You can eat foods with a “Fried to Crispy” label to gain weight.

Interestingly, Once Human’s Backpack Expansion upgrade comes in three tiers, each one with unique benefits. However, each tier has a durability period of 14 days, after which it will degrade and needs to be repaired or replaced.

Tiers	Benefits	Description
1	40% Weight Reduction	This is the basic tier, requiring minimal crafting materials. It reduces overall weight by 40%.
2	60% Weight Reduction	A more advanced tier that offers a significant weight reduction of 60%. This tier requires rarer materials to craft.
3	80% Weight Reduction	The highest tier provides the maximum weight reduction of 80%. It's the most beneficial but requires the rarest crafting materials.
