Modular Backpacks is a Vintage Story mod by Niikelion. Modular Backpacks turns vanilla backpacks into upgradeable storage gear by letting you attach addons that increase their available slots.
Why this mod is worth installing
This addon is useful for players who rely on backpacks but want to expand their capacity without replacing them with a completely different storage system.
What Modular Backpacks adds
Modular Backpacks changes the role of vanilla backpacks from fixed-capacity containers into storage items that can be expanded with attachable addons. Instead of crafting or carrying several separate packs, you can improve one backpack as your needs grow.
The main benefit is a more flexible inventory setup during exploration, gathering, and long journeys. Additional capacity can help keep tools, materials, food, and other supplies together while preserving the familiar backpack-based gameplay.
