| Promo Code | Reward Type | Fragment Amount | Additional Materials |

Step-by-Step Code Redemption Process
If you are new to the experience, finding the code redemption menu can be slightly confusing due to the game's stylized user interface. Follow these straightforward steps to claim your free rewards:
Prepare Your Account
Ensure you have liked the game on its official Roblox experience page and joined the Project Mirror Labyrinth Roblox Group.
Launch the Experience
Open Roblox and launch Project Mirror Labyrinth. It is recommended to play with a keyboard and mouse as controller support is currently limited.
Open the Left Menu
Once inside the lobby, press the TAB key on your keyboard or click the Menu icon located on the left side of your screen.
Navigate to Codes
Click on the Codes tab, which is positioned at the very bottom of the menu list.
Submit and Confirm
Type or paste your active code into the text field, then click the Confirm button to instantly receive your Fragments.
If a code is confirmed active but fails to reward you, leave the game and join a newer server. Older servers that have not updated to the latest patch may reject newer codes.
Gameplay Methods to Gain Fragments
While promotional codes provide a quick influx of currency, you will need consistent in-game methods to sustain your progression over time. Active gameplay loops are designed to reward strategic deck-building and successful exploration.
1. Completing Dungeon Runs
Dungeon runs are the core gameplay loop of Project Mirror Labyrinth. To initiate a run, you can either select Play from your TAB menu or walk up to and interact with the physical NO ENTRY gate in the lobby.
- Survival Rewards: The further you advance through the maze-like stages, the more Fragments you secure at the end of the run.
- Deck Optimization: Balancing your deck with a healthy mix of high-damage attack cards and reliable defense cards ensures you survive deeper encounters, maximizing your payout.
2. Luxcavation Farming
Luxcavations serve as specialized daily or weekly challenge encounters that offer concentrated rewards. Prioritizing these runs when they are available is highly recommended for players looking to optimize their weekly Fragment income.
3. Defragmenting Outfits
As you accumulate duplicate Outfits from Standard and Targeted Reflections, you can utilize the Defragmentation system. While Defragmenting primarily consumes materials like Condense and Seeds of Light to unlock passive abilities, managing your duplicate Outfits efficiently ensures your primary resources are never wasted.
| Progression System | Main Currency Required | Secondary Materials | Primary Goal |
|---|---|---|---|
| Standard Reflections | Fragments | None | Broad Outfit acquisition |
| Targeted Reflections | Fragments | None | Focused Outfit targeting |
| Outfit Defragmentation | Fragments | Condense, Seeds of Light | Unlock passive abilities & stats |
The development team schedules regular game maintenance every Tuesday at approximately 2:00 P.M.. Dungeon queues and code redemptions may be temporarily disabled during these update windows, so plan your farming sessions accordingly.
Fragment Spending Priorities
Gaining Fragments is only half the battle; spending them wisely is what separates casual players from seasoned deck-builders. Because Fragments are used across multiple systems, we recommend adhering to a strict upgrade priority list:
1. Targeted Reflections
Save your Fragments for Targeted Reflections when an Outfit that perfectly synergizes with your deck archetype becomes available. This minimizes wasted pulls.
2. Standard Reflections
If you lack a solid foundation of Outfits, spend Fragments on Standard Reflections to widen your collection and unlock basic stat boosts.
3. Skill & Passive Unlocks
Allocate leftover Fragments alongside Condense and Seeds of Light to Defragment your most reliable Outfits, securing game-changing passive abilities.
Do not spend your Fragments erratically on standard banners if a targeted banner featuring meta-relevant Outfits is on the horizon. Saving a pool of 2,000+ Fragments ensures you can fully commit when high-value Reflections drop.
Dungeon Preparation Checklist
Before launching your next dungeon run to farm Fragments, go through this checklist to ensure your character is fully optimized for survival:

- Equip your highest-stat Outfits obtained from Reflection pulls.
- Check your deck to ensure a stable balance of attack and defense cards.
- Confirm that your unlocked passive abilities from Defragmentation are active.
- Ensure you are playing on a fresh server to avoid lobby UI or menu glitches.
