The short answer for how to save in Building 0: Hakuei University is that you cannot save anywhere you want from a menu. The game uses a classic survival horror save system, combining infrequent automatic checkpoints with manual save points located in the world. To manually save your progress, you must find and interact with specific black rotary telephones.
Forgetting to use these phones is the fastest way to lose hours of progress exploring the haunted campus. This system is deliberate, designed to create tension and raise the stakes of every encounter. Relying on the game's autosave feature alone is a mistake that will punish you severely. This guide breaks down exactly how both systems work and the best strategy to ensure you never have to replay a terrifying section again.
Where to Find Manual Save Points
Your lifeline in Building 0 is the network of old, black rotary telephones scattered across Hakuei University. These are the only places you can perform a manual save. They are your absolute priority when entering a new area. When you find one, you can interact with it to open the save menu and choose one of several save slots. The game does not have a quicksave function.
Common Telephone Locations
While their exact placement can feel unpredictable, these phones tend to appear in areas that function as temporary safe havens or hubs before you delve into a more dangerous part of the campus. Keep an eye out for them in locations like:
- The Paranormal Research Club Room: Your home base often contains a reliable save point.
- Lobby & Reception Desks: Check the main desks in the Library, Administration Building, and of course, Building 0 itself.
- Staff Rooms & Offices: Professors' offices or faculty lounges are common spots for a telephone.
- Security Rooms: Any room with security monitors is a prime candidate for a save point.
Finding a phone isn't just an opportunity to save; it's a signal from the developers. A save point almost always precedes a difficult puzzle, a major story development, or a dangerous new enemy encounter. Use it as a moment to breathe, organize your thoughts, and prepare for what's coming next.

How the Autosave System Works (and Why You Shouldn't Trust It)
Building 0: Hakuei University does have an autosave system, but it's best to think of it as a safety net for game crashes, not a reliable way to preserve your progress. The game saves automatically at key moments, usually signified by a small, unobtrusive icon appearing in a corner of the screen. You cannot trigger this manually, and the save slots are separate from your manual saves.
Key Autosave Triggers
The game will typically create an automatic checkpoint at the following moments:
- Entering a Major New Area: For example, the first time you step foot inside the infamous Building 0.
- After Critical Cutscenes: Once a major, non-interactive story sequence concludes.
- Before a Major Encounter: The game is often kind enough to save just before a boss fight or a scripted chase sequence begins.
- Upon Completing a Major Chapter: Progress is usually saved when one story act transitions to the next.
However, the gap between these autosaves can be enormous. You might solve three complex puzzles, find four crucial documents, and unlock two new shortcuts in the hour between checkpoints. If you are killed by a random ghost or fail a puzzle, you will be sent back to the last autosave, potentially losing all of that painstaking progress. Do not rely on it. Always prioritize finding the next telephone.

The Best Strategy for Saving Your Game
To avoid the frustration of lost progress, you need a disciplined saving strategy. Modern games have trained us to expect constant autosaves, but Building 0 demands an older, more deliberate approach. Treat every manual save as a precious resource.
The Golden Rules of Saving
-
Save in a New Slot Occasionally: While it's fine to overwrite your main save file most of the time, it's wise to create a backup in a different slot every few hours. This protects you from the rare but terrifying possibility of saving yourself into an unwinnable situation (e.g., saving with no healing items right before a boss you can't beat).
-
Save After Any Significant Accomplishment: Did you just spend 20 minutes cracking a safe code? Find a key that opens a new wing of the building? Uncover a shocking truth about the university's past? Backtrack to the last phone you saw and lock in that progress immediately. It may feel tedious, but it's far less tedious than re-solving that puzzle from scratch.
-
Save Before Exploring the Unknown: If you open a door and see a long, dark hallway you've never been down, turn back. Go save first. The game's level design is full of points of no return and sudden, lethal threats. Treat every new area as hostile until proven otherwise.

Frequently Asked Questions About Saving
Here are quick answers to the most common questions about the save system in Building 0: Hakuei University.
Can you save anywhere from the menu?
No. You can only save at fixed manual save points in the game world, which are black rotary telephones. There is no option to save from the pause menu.
How do I know if the game is autosaving?
A small, subtle icon will briefly appear on-screen, typically in the bottom-right corner. This indicates a checkpoint has been created. Pay attention, as it's easy to miss.
What happens if I quit the game without saving?
You will lose all progress since your last save, whether it was a manual save at a telephone or an automatic checkpoint. When you continue, you will resume from whichever of those two events happened most recently.
Are there save points before every boss?
Almost always. The game is generally fair about placing a telephone in a room or hallway shortly before a major boss encounter or a difficult chase sequence. If you find a phone and a stock of healing items in the same room, you should be on high alert.
Final Thoughts
The save system in Building 0: Hakuei University is a core part of its design, not an oversight. It forces you to think strategically about risk and reward, making every step into the unknown feel meaningful and tense. By understanding the roles of both manual and automatic saves—and by always prioritizing the telephones—you can conquer the horrors of Hakuei University without losing your mind to lost progress.
