All Shelter Upgrades and License Keys in Pragmata (April 2026)

Pragmata throws you into a ruined lunar research station with Diana, a mysterious girl who depends on you for survival. Your home base, called the Shelter, starts with locked terminals, weak weapons, and limited crafting options. Shelter upgrades change all of that. Every Shelter License Key you collect expands your base, unlocks new weapons, and opens up abilities that make combat and exploration far more manageable.

In this guide, I break down every Shelter upgrade and License Key in Pragmata so you know exactly what each level unlocks, where to find each key, and which upgrades to prioritize first. Whether you are grinding through the Solar Power Plant or pushing into the Lunum Mines, this reference has you covered for 2026.

What Are Shelter Upgrades in Pragmata?

Shelter upgrades in Pragmata are progression milestones tied to Shelter License Keys. Each key you earn raises your Shelter level, which directly expands the REM Replicator, unlocks new weapons and abilities, and opens additional base facilities like Training Simulations and the Stamp Board.

You earn Shelter License Keys by defeating sector bosses at the end of each major area. The progression is linear and story-gated, meaning you cannot skip ahead. Each boss drops a specific key that corresponds to one Shelter level, so clearing a sector always pushes your base forward.

Lunafilament is the currency that powers these upgrades. You collect it from exploration, combat encounters, and specific resource nodes scattered across each sector. The REM Replicator inside the Shelter converts Lunafilament into weapon blueprints, ability modules, firmware updates, and unit printer items. Understanding when to spend Lunafilament and when to save it is a big part of optimizing your playthrough.

One important detail that caught me off guard early on: weapons share upgrade limits. Your firmware upgrade cap rises with each Shelter level, but all weapons draw from the same pool. If you pour upgrades into one weapon, you may not have enough capacity left for others until you hit the next Shelter level.

All Shelter Upgrades and License Keys in Pragmata

There are five Shelter levels in total. Levels 1 through 4 come from defeating sector bosses during the main story, while Level 5 unlocks after completing a post-game mission. Here is every level broken down with what it unlocks and how to get the key.

Shelter Level 1: Solar Power Plant

The first Shelter License Key drops from the SectorGuard boss at the end of the Solar Power Plant sector. This is the earliest progression gate in the game, and it unlocks your foundational loadout options.

Level 1 unlocks the Riot Blaster, Charge Piercer, and Sticky Bombs as craftable weapons at the REM Replicator. You also gain access to the first tier of Training Simulations, which let you practice combat mechanics and earn bonus rewards through the Stamp Board. Basic firmware upgrades become available here, allowing you to start boosting weapon stats.

This is where you learn the crafting loop. You gather Lunafilament from the Solar Power Plant, return to the Shelter, and use the REM Replicator to build your initial weapon set. I recommend crafting all three weapons at this stage since you need to experiment with each one to find your preferred playstyle.

Shelter Level 2: Mass Production Array

The second Shelter License Key comes from the Gigantic Bot boss in the Mass Production Array. This sector ramps up enemy density and introduces new combat patterns that make your upgraded loadout essential.

Level 2 unlocks the Pulse Carbine and Homing Missiles at the REM Replicator. Your firmware upgrade limit increases, giving you more room to enhance both old and new weapons. The Unit Printer expands to offer additional items, and the Stamp Board gains new reward tiers.

The Pulse Carbine becomes a go-to weapon for many players at this stage. Its rapid-fire capability pairs well with the homing missiles for crowd control. If you have been saving Lunafilament, now is a good time to spend some on these new options.

Shelter Level 3: Terra Dome

Defeating the Large Bot boss in the Terra Dome grants the third Shelter License Key. The Terra Dome introduces environmental hazards and more complex encounter layouts that test your upgraded arsenal.

Level 3 unlocks the Decoy Generator and EC Thrusters. The Decoy Generator creates a holographic distraction that draws enemy fire, which is extremely useful against the heavier enemies you encounter from this point forward. The EC Thrusters improve your mobility, letting you close gaps or escape danger faster.

This level also expands your firmware upgrade cap again and adds new Training Simulation challenges. The Cabin Stamps system introduces additional collectibles to track, and Diana gains new dialogue options inside the Shelter that hint at story developments.

Shelter Level 4: Lunum Mines

The LunaDigger boss guards the fourth Shelter License Key deep in the Lunum Mines. This is the final story-gated upgrade, and it unlocks some of the most impactful abilities in the game.

Level 4 unlocks the Impact Barrier, Object Scan, and Auto-Hacking. The Impact Barrier gives you a protective shield during combat encounters. Object Scan reveals hidden items and resources in the environment, making exploration far more rewarding. Auto-Hacking simplifies the hacking minigames that block progress in later sectors.

These three unlocks change how you approach the game. Object Scan alone can save you hours of searching for hidden resources, and Auto-Hacking removes a significant frustration point. Your firmware limits expand one final time during the story, so you have more headroom to max out your favorite weapons.

Shelter Level 5: Post-Game Mission

The fifth and final Shelter License Key does not come from a sector boss. Instead, it unlocks after completing a specific post-game mission that becomes available after you finish the main story. This is an endgame reward for players who want to fully upgrade their Shelter.

Level 5 removes upgrade limits entirely. Your firmware cap is unlocked, meaning you can fully upgrade every weapon and ability without restrictions. The REM Replicator gains access to the highest tier of crafting recipes, and all Training Simulations and Stamp Board rewards become available.

Reaching Level 5 also opens new Diana interactions in the Shelter. These conversations provide additional story context and character development that you will not find elsewhere in the game.

Shelter Upgrade Priority: What to Get First

One of the most common questions players ask on forums is which upgrades to prioritize. The answer depends on your playstyle, but there is a general order that works well for most players.

At Level 1, craft all three weapons (Riot Blaster, Charge Piercer, Sticky Bombs) to test each one. You need the combat experience to decide which fits your approach. Spend Lunafilament on the Charge Piercer first if you prefer precision, or the Riot Blaster if you like sustained fire.

At Level 2, prioritize the Pulse Carbine. Its versatility in both close and mid-range fights makes it one of the most reliable weapons through the mid-game. Hold off on maxing out Homing Missiles right away since they eat a lot of firmware capacity.

At Level 3, get the Decoy Generator before the EC Thrusters. The decoy provides immediate survivability against the tougher enemies in the Terra Dome and beyond. Mobility upgrades are nice, but staying alive matters more.

At Level 4, unlock Object Scan first. This ability reveals hidden items and resources everywhere, which directly feeds back into your upgrade economy. More resources found means more Lunafilament to spend. Auto-Hacking is the second priority since it removes a repetitive minigame from your play sessions.

Above all, resist the urge to dump all your firmware upgrades into a single weapon early on. Since weapons share the firmware cap, spreading upgrades across two or three weapons gives you flexibility when different combat situations demand different tools.

Lunafilament Economy: When to Spend and Save

Lunafilament is the backbone of your entire upgrade path, and managing it well separates a smooth playthrough from a frustrating one. No competitor guide covers this topic, but it comes up constantly in player forums.

You earn Lunafilament from three main sources: combat encounters, environmental resource nodes, and the Eco Modeling Lab. The Eco Modeling Lab becomes increasingly important as you progress because it converts raw materials into Lunafilament at higher rates than passive collection.

The biggest mistake new players make is spending Lunafilament the moment they can afford something. Early on, this is fine since upgrades at Level 1 are inexpensive. But starting at Level 2, weapon and ability costs spike sharply. If you spent everything at Level 1, you may find yourself underpowered when you reach the Mass Production Array.

My recommendation is to save roughly 30 to 40 percent of your Lunafilament when you are close to a sector boss fight. That reserve gives you immediate purchasing power when the next Shelter level unlocks new options. After you craft what you need, you can spend more freely while exploring the next sector.

Another overlooked source of Lunafilament is revisiting previous sectors with Object Scan active after you unlock it at Level 4. Hidden resource nodes that were invisible before become scannable, giving you a second pass of materials you missed the first time through.

Tips for Getting the Most Out of Your Shelter

Beyond the main upgrade path, several Shelter features deserve your attention. These smaller systems add up over the course of a playthrough.

Diana interactions inside the Shelter are more than flavor text. Talking to Diana between missions triggers dialogue that reveals story context, hints at upcoming sector challenges, and occasionally provides gameplay tips. Players on the Pragmata subreddit have noted that certain Diana conversations hint at hidden item locations in upcoming sectors, making it worth checking in with her after every major story beat.

Training Simulations are not just tutorial modes. Each tier offers timed combat challenges with score-based rewards. Completing them earns Cabin Coins and stamp progress that feed into the Stamp Board reward system. Even if you feel confident in combat, running through the simulations for each Shelter level gives you extra resources you would not get otherwise.

The Stamp Board tracks collectible stamps found throughout the game world and inside the Shelter itself. Completing stamp sets rewards you with Lunafilament, Cabin Coins, and occasionally unique cosmetic items. Check the board after every sector to see which stamps you are close to completing.

One technical note worth mentioning: some players report significant frame rate drops specifically inside the Shelter area. If you experience this, reducing graphics settings or restarting the game session usually resolves it. This issue appears to be tied to the number of active Shelter systems running simultaneously rather than general performance problems.

FAQ

Conclusion

Tracking every Shelter upgrade and License Key in Pragmata comes down to following the sector boss progression through the main story. Each of the five Shelter levels adds weapons, abilities, and base facilities that grow your combat options and exploration tools. The four story bosses (SectorGuard, Gigantic Bot, Large Bot, and LunaDigger) hand you Levels 1 through 4, while a post-game mission opens the final Level 5 that removes all upgrade restrictions.

The key takeaways are straightforward. Craft broadly at Level 1 to find your preferred weapons. Prioritize the Pulse Carbine at Level 2 and the Decoy Generator at Level 3. Unlock Object Scan first at Level 4 to feed your Lunafilament economy. And save your Lunafilament reserves for major milestones rather than spending the moment you can afford something. With these Pragmata Shelter upgrades in order, you will have the tools you need for every sector the game throws at you.
