Quick answer
The practical Tidy Up History route is system-driven rather than a guessed room list. In every accessible area, first clean and repair what your current abilities permit. During that pass, collect keys and read Knowledge Books. Then identify and place artifacts, move named fossils toward their mounts, and spend XP on abilities that unlock the next visible blocker. Open newly available doors and repeat. Apply labels and late repair types during a controlled second pass, then audit every room for completion. This order follows confirmed gameplay systems while avoiding unsupported claims about an exact fixed key sequence or room count.
Phase 1: learn the entrance loop
Begin in the museum areas already open. Follow the walls, remove available dirt and water, clear accessible webs, and complete every repair prompt your current toolset supports. Place only objects with a clear highlighted destination. Move unknown artifacts and fossils into separate, tidy staging groups rather than carrying them through locked corridors.
Collect visible keys and Knowledge Books during this first pass. Look above eye level and around furniture, not only at the floor. Repairs, cleaning, and placements provide XP in collected gameplay, so the opening work is also your path to the first ability choices. Do not worry when a room remains unfinished because some interaction types belong to later progression.
- Clear open spaces and establish staging areas.
- Finish current cleaning and repair prompts.
- Collect keys and Knowledge Books in the same sweep.
- Place confirmed artifacts and fossil pieces.
- Save unresolved tasks for the next ability pass.
Phase 2: open the first locked galleries
Use each named key on its matching exhibit door. The research confirms Egypt, ancient China, Japan/Korea, Islamic World, and dinosaur-related progression among the museum areas, but it does not provide an authoritative universal sequence for every current patch. Let the names in your inventory and on the doors direct the route.
Upon opening a gallery, search it before transporting every related object. Find its knowledge, keys, repair work, boxes, and display highlights. A newly opened room can explain artifacts already staged elsewhere or contain a key for a different wing. Finish an information pass first, then make grouped carrying trips.
Phase 3: build knowledge and sort artifacts
Read Knowledge Books as soon as they are found. Revisit unknown-object piles after each useful book and separate newly identified items by destination. Take one room group at a time, follow the game's highlight, and place objects in confirmed slots. Do not rely on appearance when the interface still shows uncertainty.
If a gallery stalls, distinguish information problems from condition problems. Question-mark objects indicate missing knowledge; an empty highlight indicates a missing placed item; a low room condition may indicate cleaning or repair work. Solving the correct category prevents random museum-wide searching.
Phase 4: use XP and abilities to reopen old work
Choose abilities based on tasks visible in several accessible rooms. Official update notes confirm Historian, Contractor Vision, and Lost & Found as optional helping abilities, a togglable Historian, a reopenable skill tree, and stored points. You can inspect the museum before committing a point.
After an ability expands your restoration options, revisit earlier galleries. Floors, walls, lights, containers, labels, highlighting, or other interactions may now be available. These return visits provide more XP and can reveal why a room stopped below completion. Exact node order and level requirements remain governed by the live skill tree.
Phase 5: assemble dinosaur exhibits
Move named fossil pieces to matching highlighted mounts. Collected footage confirms multiple dinosaur displays and shows bones spread across the museum rather than contained in one fossil room. Group pieces by dinosaur or gallery and transport complete batches after the relevant door opens.
Pieces can be attached in the order found; recorded gameplay does not establish a required bottom-up assembly. When one slot remains empty, search remote galleries, containers, staging piles, and the floor around the mount. After the skeleton is assembled, finish the surrounding room's cleaning, repairs, lights, and labels.
Phase 6: apply labels and finish rooms
Use the label interface after artifact identities and displays are stable. Official updates confirm label drawers and improved selector navigation. Work one exhibit group at a time, matching the game's identified names rather than guessing from silhouettes. This is faster and safer than applying labels while objects are still moving between rooms.
For every room, check condition, artifacts, knowledge, labels, and any special assembly. Walk the perimeter, look up, and inspect behind displays. Use the available helping abilities to audit only after a manual pass. A room that looks polished can still hide a web, repair point, unlit fixture, or empty slot.
Phase 7: resolve progression blocks
If every visible door is locked, return to the newest open galleries and search for keys and books. If artifacts remain unknown, prioritize knowledge. If room condition is stuck, prioritize repairs and ability-enabled highlighting. If one fossil is missing, search all recently opened spaces and staging piles. This decision tree follows the confirmed systems without assuming one scripted answer.
For a genuine recovery case, the built-in Cheats menu includes 21122124 for Level Up and 42144432 for the Egypt Key. Keep a clean save before using them because achievement effects are not fully verified in the project research. Missing key and object issues have appeared in patch notes, so update the game and consult official Steam discussions when normal progression is exhausted.
Final pass: museum and achievement audit
The project brief confirms 25 Steam achievements. Before declaring the run complete, verify every accessible wing, all visible room systems, Knowledge Books, placed artifacts, labels, assembled skeletons, and the ability work that became available late. Then compare the live Steam achievement panel with your completed categories.
The current project files do not contain a verified title-by-title official achievement table or every exact item coordinate. Those details remain to be confirmed rather than guessed. Use the 100% guide for the final checklist and the specialist pages whenever one category remains incomplete.
