Pragmata has a total of 6 Cartridge Holder locations scattered across its lunar base, and finding every one of them is the difference between scraping through encounters and comfortably surviving them. Each Cartridge Holder you collect adds one extra slot for Repair Cartridges in Hugh’s inventory, which directly increases how many times you can heal before heading back to The Shelter. In this guide, I will walk you through all Cartridge Holder locations in Pragmata, including the two found in explorable sectors and the four rewarded through the Cabin Stamp Club.
Repair Cartridges are your primary healing method in Pragmata, and they do not regenerate on their own. You start with a limited number of slots, and every enemy encounter, boss fight, and Red Zone exploration chips away at your supply. Cartridge Holders solve this problem by permanently increasing your carry capacity, so you can stock up before venturing into dangerous territory. Whether you are pushing through the main story or aiming for 100% completion, tracking down all 6 Cartridge Holders should be a top priority.
Here is the full list of every Cartridge Holder location in Pragmata. I have organized them by area so you can quickly check which ones you still need.
Two of the six Cartridge Holders are found out in the world during exploration. The other four come from completing Stamp Boards at the Cabin Stamp Club back in The Shelter. I will cover each one in detail below.
Before jumping into the specific locations, it helps to understand exactly why these collectibles matter so much. Pragmata is a game about exploration and resource management on a desolate lunar research station. Hugh and Diana navigate through hostile zones filled with malfunctioning security bots and environmental hazards. Repair Cartridges are the only reliable way to restore health during these expeditions.
Unlike some games where healing items regenerate or can be crafted on the spot, Repair Cartridges in Pragmata are finite. You pick them up from Safe Boxes, find them in the environment, or purchase them with resources. Once they are gone, they are gone until you restock. This makes your maximum carry capacity incredibly important.
Each Cartridge Holder permanently adds one extra slot to Hugh’s Repair Cartridge inventory. With all 6 collected, you gain six additional healing opportunities per outing. In practice, this means you can push deeper into sectors, take on tougher enemies, and spend less time backtracking to The Shelter to resupply. For anyone tackling the harder encounters in the later chapters, having all Cartridge Holders is practically mandatory.
The first Cartridge Holder you can find in the world is located in Sector 1, specifically within the Solar Power Plant area at Block 3: The Concourse. This is one of the earlier sectors you gain access to, but you may need certain tools before you can actually reach the holder depending on your progression.
To find it, start by taking the Tram link to the Solar Power Plant. Once you arrive, navigate toward Block 3 and look for The Concourse area. This is a large open section with multiple pathways and platforms. Follow the main corridor until you spot a side passage leading to a medical room. The medical room is identifiable by its bright lighting and the distinctive orange medical device sitting on the wall inside.
That orange device is your Cartridge Holder. Interact with it to collect it, and Hugh will gain one additional Repair Cartridge slot immediately. The room also typically contains a few extra supplies, so make sure to grab everything before leaving.
One thing I want to point out: the entrance to this medical room can be easy to miss if you are moving quickly through the area. The doorway is set back from the main path and partially obscured by a structural column. If you have passed through The Concourse and did not spot a medical room, backtrack slowly and check the left side of the corridor. Using the beacon system to mark nearby points of interest can also help pinpoint its location on your minimap.
The second explorable-world Cartridge Holder sits in Sector 2 within the Mass Production Array area at Block 4: Business District. This location is further into the game and requires more careful navigation than the first one.
From the Mass Production Array arrival point, head toward Block 4. The Business District is a multi-level zone with several interconnected corridors and offices. Several players on forums have noted that this area can feel disorienting because of its repeating architecture and multiple elevation changes, so take your time navigating.
Work your way through the Business District until you reach the central office complex. Look for a side corridor that branches off from the main walkway near the large window overlooking the lunar surface. Follow this corridor down one level and you will find a small alcove containing the Cartridge Holder. Like the first one, it appears as an orange medical device mounted on the wall.
This particular Cartridge Holder may require a specific tool or ability to access. If you reach the area and cannot find a way through, you likely need to continue the main story and return later with the appropriate equipment. Backtracking is a common theme in Pragmata’s collectible system, and some areas only become fully accessible after you have acquired key items from later chapters.
My advice is to check this location during your first visit to Sector 2, but do not stress if you cannot reach it right away. Make a mental note or drop a beacon, then return once you have more tools at your disposal. The game is designed so that most players will pass through this area multiple times, giving you natural opportunities to check back.
Four of the six Cartridge Holders in Pragmata come from the Cabin Stamp Club, which is located back in The Shelter. This is the central hub area where you return between missions, and it houses a mini-game system that rewards dedicated players with valuable upgrades including Cartridge Holders.
The Cabin Stamp Club uses a Bingo-style Stamp Board system. You earn Cabin Coins by completing various activities throughout the game: defeating enemies, finding collectibles, completing side objectives, and progressing through the story. You then spend these Cabin Coins to place stamps on a Bingo card. Completing rows, columns, or diagonals on the Stamp Board unlocks specific rewards.
There are 4 Stamp Boards in total, and each one gets progressively more expensive to complete. The rewards also get better as you advance through the boards. Each of the 4 Stamp Boards includes at least one Cartridge Holder as a reward, though the exact position on the board varies. Some boards give the Cartridge Holder for completing a specific line, while others might offer it as a milestone reward for stamping a certain number of spaces.
The first Stamp Board is the cheapest and most accessible. You will unlock it early in the game, and most of the stamps require Cabin Coins earned from basic activities. Focus on completing a full row or column to claim the Cartridge Holder reward. This board also includes smaller rewards like extra Lunafilament and crafting materials along the way.
Stamp Board 2 ramps up the Cabin Coin requirements slightly but follows the same pattern. Work toward completing lines to unlock the Cartridge Holder. By this point in the game, you should have a steady income of Cabin Coins from regular exploration and combat, so this one should come naturally if you are playing through the content.
The third board requires more stamps and more Cabin Coins per stamp. The Cartridge Holder reward is typically tied to a diagonal completion or a full board clear bonus. I recommend saving up your Cabin Coins before starting this board so you can place multiple stamps in one session rather than chipping away at it slowly.
The final Stamp Board is the most expensive but also the most rewarding. Completing it earns you the last Cartridge Holder along with other end-game rewards. By the time you are working on Board 4, you should have explored most of the lunar base and accumulated a significant stockpile of Cabin Coins. The completion requirements are steeper, but the payoff is worth it for that final inventory upgrade.
Here are a few strategies I found helpful when working through the Stamp Boards:
Hunting down every Cartridge Holder takes patience and a willingness to explore off the main path. Here are my top tips to make the process smoother.
Look for orange medical devices. Both of the world-based Cartridge Holders appear as orange devices mounted on walls, usually inside medical rooms or small alcoves. If you see something that looks like a medical station, check it out. They are distinct from the red pedestals used for other interactables.
Use beacons to mark locations. The beacon system in Pragmata lets you tag points of interest on your map. If you spot a medical room but cannot access it yet, drop a beacon so you can easily find it later. This is especially helpful in the Business District where navigation gets tricky.
Expect to backtrack. Pragmata is designed around revisiting areas with new tools. Do not assume you have missed a Cartridge Holder just because you cannot reach it during your first pass. Continue the story, acquire new abilities, and return to previously explored zones.
Check medical rooms and side corridors. Cartridge Holders are almost always found in medical rooms or small side passages rather than out in the open. If you are running through main corridors only, you will miss them. Take the time to explore every branch.
Prioritize the Cabin Stamp Club. Since 4 of the 6 Cartridge Holders come from the Cabin Stamp Club, this should be your main source. Check back at The Shelter regularly between missions to spend your Cabin Coins and progress through the Stamp Boards.
Explore thoroughly on first visits. While backtracking is expected, you can save yourself time by being thorough on your first visit to each sector. Check every room, scan every corner, and interact with anything that looks unusual. A five-minute detour on your first pass can save you a 30-minute backtrack later.
Pragmata has several types of collectibles, and it is easy to confuse Cartridge Holders with similar upgrades. Here is how they compare.
Cartridge Holders increase the number of Repair Cartridge slots in Hugh’s inventory. More slots means you can carry more healing items at once, giving you greater survivability in combat and during long exploration runs. There are 6 Cartridge Holders total.
Storage Expanders are a separate collectible type that increases general inventory capacity. While Cartridge Holders specifically affect Repair Cartridges, Storage Expanders affect other item types including key materials and consumables. There are 5 Storage Expanders scattered throughout the lunar base. Both collectible types are worth pursuing, but Cartridge Holders have a more direct impact on your ability to survive tough encounters.
Beyond Cartridge Holders and Storage Expanders, Pragmata includes Safe Boxes containing resources, Mod Boxes that provide ability upgrades, Escape Hatches that serve as fast travel points, and Mini Cabins that offer rest stations. Some of these are tied to progression while others are purely optional. For players aiming at 100% completion, tracking down every collectible type becomes a major goal.
My recommendation for a first playthrough is to prioritize Cartridge Holders over Storage Expanders. The extra healing capacity has a more immediate impact on gameplay, especially during boss encounters and Red Zone sections where damage is unavoidable. Storage Expanders are nice to have, but you can manage inventory space more easily through careful resource planning.
Cartridge Holders in Pragmata permanently increase Hugh’s Repair Cartridge carry capacity by one slot each. Repair Cartridges are your primary healing items, and they do not regenerate over time, so having more slots means you can survive longer between visits to The Shelter.
There are 6 Cartridge Holders total in Pragmata. Two are found in explorable areas (Sector 1 Solar Power Plant and Sector 2 Mass Production Array), and the other four are rewarded through the Cabin Stamp Club by completing Stamp Boards at The Shelter.
The 6 Cartridge Holders are located at: Sector 1 Solar Power Plant Block 3 The Concourse (medical room), Sector 2 Mass Production Array Block 4 Business District (side corridor), and four from Cabin Stamp Club Stamp Board completion rewards at The Shelter.
To increase Repair Cartridge capacity in Pragmata, collect Cartridge Holders found throughout the lunar base. Each one adds a permanent extra slot. You can find 2 in the field at the Solar Power Plant and Mass Production Array, plus earn 4 more by completing Stamp Boards at the Cabin Stamp Club.
No, you cannot permanently miss Cartridge Holders in Pragmata. All locations remain accessible throughout the game, and you can backtrack to any sector to collect ones you passed over earlier. Some may require specific tools to reach, but you can always return with the right equipment.
Cartridge Holders are permanent inventory upgrades that carry over with your character progression. Since they expand your base Repair Cartridge capacity, you retain the benefit in any continued playthrough of Pragmata.
Tracking down all Cartridge Holder locations in Pragmata gives you a significant advantage throughout the entire game. Two holders are found during world exploration at the Solar Power Plant’s Concourse and the Mass Production Array’s Business District. The remaining four come from completing Stamp Boards at the Cabin Stamp Club in The Shelter. Together, they give Hugh six extra Repair Cartridge slots, turning tight encounters into manageable fights and letting you push further into the lunar base without constant resupply trips.
My suggestion is to grab the two world-based Cartridge Holders as soon as you reach their respective sectors, and check in on the Cabin Stamp Club between every mission. The Cabin Coins add up quickly, and working through the Stamp Boards steadily is far less tedious than trying to complete them all at once near the end of the game. With all 6 Cartridge Holders in hand, you will be well prepared for everything Pragmata throws at you on the road to 100% completion.
