Bunker Tidy Up item sorting: Tips & Tricks Guide

Bunker Tidy Up item sorting is built around categorizing scattered supplies across a large underground shelter. The game contains 17,437 supplies, dozens of shelf sections, and more than 100 unique item types. Your goal is to identify each item, carry it to the correct category, and complete shelves to earn upgrade stars.

The bunker is divided into practical groups such as groceries, preserved foods, survival equipment, medicine, weapons and protection, books, household supplies, technology, and pet food. Items may look similar at a glance, so the fastest approach is to learn the category logic instead of moving randomly between shelves.

Video Highlights:

• The bunker contains two main floors filled with scattered supplies.
• Shelf categories include food, medicine, survival, books, weapons, household items, and technology.
• Carry capacity and magnet upgrades significantly reduce travel time.
• Item placement feedback helps distinguish wrong shelves from unfinished shelves.

When an item is placed on a shelf, watch the visual feedback before moving on. A red result indicates that the item does not belong in that location. A yellow result indicates a valid placement that may still be incomplete. This distinction matters because many shelves require a complete set before the game awards progress.

The most efficient sorting route begins with categories that have visually distinct items or relatively manageable quantities. Large equipment is especially useful early because it is easy to spot in crowded piles. Books are also efficient once you understand their subject-based categories.

Use the following grouping rules as a quick reference:

Books deserve special attention because their covers and titles correspond to different shelf groups. A guide about field surgery belongs with medicine, while a book about animal tracks belongs with hunting and foraging. Repair manuals usually belong with technology and repair, while underground living and community books may use separate life-in-the-bunker sections.

Do not assume that real-world logic always matches the game’s classification. Some items may appear intuitive but belong to a different shelf than expected. For example, MREs are treated as survival equipment, while toilet paper is categorized as a household supply. When uncertain, test one item and record the result mentally before collecting the rest.

A reliable route reduces unnecessary stair trips and keeps your inventory organized. The following method works particularly well during the early and middle stages of a cleanup.

The magnet is most effective when used selectively. It is tempting to activate it whenever the cooldown ends, but the best value comes from shelves that are only a few items short. If a category contains hundreds of supplies, manually gather a small starting group first and then use the magnet to finish the remaining set.

The bunker layout also rewards movement upgrades. Higher movement speed reduces long trips, while jump upgrades can help you cross railings and reach elevated areas without always using the stairs. Timing jumps near railings or using nearby furniture can shorten routes, although careful positioning is required.

Stars earned from completing shelves can be spent on skills. The strongest early improvements are the ones that reduce travel and increase the number of supplies you can carry.

Start with carrying capacity because it affects every later trip. The early capacity increases make a noticeable difference, especially when moving large equipment or groups of identical items. After that, improve the magnet so it can locate more matching objects and operate with a shorter cooldown.

Recommended upgrade priorities:

The Fly Away ability is powerful but depends on discovery. It generally works best after the game already knows where an item belongs. If a supply has never been placed on its correct shelf, the ability may not know how to handle it. For that reason, manually place at least one example of every item type before relying on automated placement.

The same principle applies to the Auto Loader. It improves the speed of repeated placement, but it does not replace category knowledge. Automation is strongest after you have established a reliable sorting system and cleared the most confusing shelves.

A clean bunker requires patience because many categories contain large quantities of similar supplies. Track progress by shelf rather than by individual item whenever possible. Completing a shelf provides a clearer sense of advancement and helps generate stars for future upgrades.

Use this final checklist before considering a floor complete:

• Check behind and beneath large piles.
• Inspect both sides of stairways and railings.
• Search tables, couches, and raised platforms.
• Revisit shelves that show valid but incomplete placement.
• Use the magnet on categories with only a few missing items.
• Confirm that no red placement feedback remains.
• Look for isolated books, batteries, pet food, and small jars.
