Upgrading rooms in Blue Prince is a crucial mechanic that enhances your efficiency and unlocks powerful bonuses for future runs. However, the process requires finding rare Upgrade Disks and accessing Terminals scattered throughout the Mt. Holly Estate. This guide covers everything you need to know about upgrading floorplans, including Upgrade Disk locations, how Terminals work, and the benefits of room enhancements.
How Room Upgrades Work in Blue Prince
To upgrade a room, you need two key components:
An Upgrade Disk – A rare item found in specific locations.A Terminal – A computer interface where you can insert the disk to apply upgrades.Where to Find Terminals
Terminals are located in the following rooms:
- The Office (Requires a Gem to enter)
- The Shelter (No Gem required)
- The Security Room (Requires a Gem)
- The Laboratory (Requires a Gem)
Since the
Shelter doesn’t require a Gem, it’s the most accessible Terminal early in the game.
How Upgrading Works
Once you have an Upgrade Disk:
Approach a Terminal and interact with it.Insert the Upgrade Disk.The game will randomly select a room from your catalog to upgrade—you cannot choose which one.You will then be given a choice of enhancements for that room.For example, the first time you upgrade the
Courtyard, you may see these options:
- Rewards +2 Gems
- Includes 5x Dig Spots
- CORRIYARD is always left unlocked
Once you select an upgrade,
all future instances of that room will include the chosen bonus. Some upgrades even replace the original room with an improved version (like the
Corriyard replacing the
Courtyard).
Upgrade Disk Locations
Upgrade Disks are rare, but several have been found in the following rooms:
1. The Office
- Location: On the main desk.
- Bonus: Conveniently placed right next to a Terminal, making it an easy first upgrade.
2. The Garage
- Location: Inside the trunk of the car.
- Requirements: You’ll need the Car Keys to unlock both the Garage door and the trunk.
3. The Great Hall
- Location: Behind one of the seven locked doors.
- Tip: Bring a Lock Pick to avoid wasting Keys.
4. The Foundation
- Location: On a box in the underground section, accessible via the elevator.
5. Her Ladyship’s Chamber
- Location: On the beauty desk near Her Ladyship’s Diary.
More Upgrade Disk locations may be discovered as players explore further. This guide will be updated with new findings.
Why Upgrading Rooms Matters
Room upgrades provide permanent enhancements that carry over into future runs, making each expedition more efficient. Some key benefits include:
- Increased resource generation (e.g., extra Gems, Dig Spots).
- Unlocked shortcuts (e.g., certain rooms staying open by default).
- New room variants (e.g., the Corriyard replacing the Courtyard).
The more upgrades you acquire, the stronger your future runs will be, allowing you to delve deeper into Mt. Holly Estate with better tools and rewards.
Tips for Efficient Upgrading
Prioritize the Shelter Terminal – Since it doesn’t require a Gem, it’s the easiest to access early on.Save Lock Picks for the Great Hall – One of its doors hides an Upgrade Disk, and using a Lock Pick conserves Keys.Explore Thoroughly – Upgrade Disks are rare, so check every corner of high-value rooms.Plan Your Upgrades – Some room enhancements are more impactful than others (e.g., extra Gems can speed up future runs).Final Thoughts
