Introduction to Project Mirror Labyrinth Fragments
In the tactical world of project mirror labyrinth, a Roblox roguelite deck builder heavily inspired by Slay the Spire, Library of Ruina, and Limbus Company, progression relies entirely on managing your resources strategically. Among these resources, project mirror labyrinth fragments stand out as the primary currency required to unlock the game's depth.
Whether you are looking to pull top-tier Outfits from standard banners or target specific builds, you will need a steady flow of this essential currency. This guide outlines the most efficient pathways to accumulate fragments, upgrade your collection, and dominate the labyrinth.

Fragments should not be spent immediately on single pulls. Saving your fragments for multi-pulls or targeted reflection banners yields far better long-term progression for your account.
Active Codes for Free Fragments
One of the fastest ways to kickstart your collection of project mirror labyrinth fragments is by redeeming active promotional codes released by the developers. These codes provide a substantial boost, allowing new players to bypass the early grind and immediately invest in Outfits and passive abilities.
The table below lists all currently functional codes as of July 2026.
| Active Code | Reward Details | Primary Resource Type | Expiry Status |
|---|---|---|---|
| UrbanPlague | 405 Fragments | Currency | Active (July 2026) |
| OfficeDelay | 1,620 Fragments | Currency | Active |
| NepoOffice | 405 Fragments | Currency | Active |
| FauvistStudents | 405 Fragments | Currency | Active |
| Welcome | 350 Fragments, 500 Condense, 3 Seeds of Light | Starter Bundle | Active |
To prevent error messages when entering codes, you must first like the game on Roblox and join the official Project Mirror Labyrinth community group. Skipping this step will cause the redemption menu to reject valid codes.
How to Redeem Codes Step-by-Step
Redeeming your codes is straightforward, but the menus can sometimes be confusing for players new to the interface. Follow these exact steps to claim your free rewards.
Join the Roblox Community
Navigate to the Roblox platform, log into your account, and join the official Project Mirror Labyrinth community group. Don't forget to leave a 'Like' on the game's main experience page.
Launch the Game
Open the Roblox client and launch Project Mirror Labyrinth. Ensure you are playing with a keyboard and mouse, as controller support is currently not fully implemented.
Access the Main Menu
Once inside the game lobby, press the TAB key on your keyboard or click the Menu icon located on the left side of your screen.
Open the Codes Tab
Scroll to the bottom of the menu list and select the Codes button. A text entry pop-up window will appear on your screen.
Enter and Confirm
Type or copy-paste your chosen code exactly as written into the text box. Click the Confirm button to instantly receive your fragments and upgrade materials.
All codes in this game are strictly case-sensitive. Entering "welcome" instead of "Welcome" will result in an invalid code error.
Defragmentation and Progression Systems
Accumulating project mirror labyrinth fragments is only the first half of the equation. To truly strengthen your deck and survive the deeper, procedurally generated dungeon floors, you must understand how to spend your resources on Outfits and passive upgrades.
The progression loop is structured around three core pillars:
1. Reflections Banners
Spend your hard-earned fragments on Targeted Reflections or Standard Reflections. These banners function as the gacha system, rewarding you with unique Outfits that alter your base stats and deck capabilities.
2. Outfit Collection
Each Outfit you acquire grants distinct stat adjustments and defensive or offensive modifiers. Collecting a diverse roster of Outfits allows you to build highly specialized decks for different dungeon challenges.
3. Defragmentation
Once you find an Outfit that fits your playstyle, use a combination of fragments, Condense, and Seeds of Light to Defragment it. This process unlocks powerful, game-changing passive abilities.
Currency and Material Breakdown
To optimize your farming, you must know exactly what each material does and where to allocate it.
| Material Name | Primary Acquisition Source | Practical Gameplay Use | Priority Level |
|---|---|---|---|
| Fragments | Codes, Dungeon runs, Encounters | Drawing Outfits, buying Reflections, unlocking skills | High (Core Currency) |
| Condense | Code rewards, Special milestones | Required for Defragmenting Outfits | Medium (Upgrade Material) |
| Seeds of Light | Rare code drops, Boss encounters | Unlocking high-tier passive abilities | High (Endgame Progression) |
| Mega Reflection Ticket | Special events, Milestone codes | Grants a free pull on the Mega Reflection banner | High (Premium Voucher) |
Use the Welcome code immediately upon starting your account. The 500 Condense and 3 Seeds of Light provided in this bundle are incredibly rare early on and should be saved specifically for defragmenting your first S-tier Outfit.
Dungeon Farming and Weekly Maintenance
While codes provide a massive initial injection of resources, active gameplay is your primary source of sustainable project mirror labyrinth fragments over time. Completing dungeon runs and defeating enemies in the maze-like stages will steadily build your fragment reserves.
Tips for Efficient Dungeon Farming
- Balance Your Deck: Do not neglect defense cards. A deck loaded purely with attack cards will quickly fall to high-damage bosses in the deeper floors.
- Pathing Choices: When navigating the labyrinth, plan your route to target high-reward encounters that drop fragments and upgrade materials.
- Utilize the NO ENTRY Gate: You can easily start a dungeon run by interacting with the physical NO ENTRY gate in the lobby or using the TAB menu.
Scheduled Downtime Alert
Keep in mind that the game undergoes scheduled weekly maintenance to apply patches, balance cards, and rotate code rewards.
- Maintenance Day: Every Tuesday
- Approximate Time: 2:00 P.M.
- Impact: Server access, dungeon matchmaking, and code redemptions will be temporarily unavailable during this window.
If you attempt to redeem a code immediately following a game update and receive an error, log out of Roblox and rejoin a newly updated server. Older servers often run on outdated code lists.
