Sector 3 – Terra Dome in Pragmata (June 2026) Complete Guide

If you have made it this far in Capcom’s lunar adventure, congratulations are in order. You have survived Sector 1 and Sector 2, dealt with IDUS, and now you are staring down the most ambitious area in the game so far. Our Pragmata Walkthrough: Sector 3 – Terra Dome guide covers every block, every collectible, and every frustrating enemy encounter from start to finish.

Sector 3 is where Pragmata stops holding your hand. The Terra Dome is a massive, multi-layered biodome on the lunar surface, and it introduces new enemy types, new weapons like the Pulse Carbine and Sticky Bombs, and a boss fight that has been giving players trouble since launch. Whether you are going for 100% completion or just trying to get through the story, this walkthrough has you covered.

Is Pragmata hard? Yes, especially in Sector 3. The game has a steep difficulty curve that some players compare to soulslike titles, though Pragmata is not technically a soulslike. It is a story-driven action-adventure from a AAA studio (Capcom), blending hack-and-shoot combat with environmental puzzles and hacking mechanics. Sector 3 is where all those systems come together in ways that demand real mastery.

I have played through the Terra Dome multiple times to map out every Safe Box, every Read Earth Memory (REM), every Gen Chip, and every Pure Lunum deposit. This guide is organized block by block, so you can follow along from the beginning or jump to whichever section you are currently stuck on.

Terra Dome Entrance Walkthrough (Block 01)

Getting Started in the Terra Dome

When you first enter the Terra Dome, take a moment to appreciate the scenery. After the sterile corridors of Sectors 1 and 2, the lush green environment is a welcome change. Do not get too comfortable, though. The Terra Dome Entrance sets the tone for the entire sector, throwing mixed enemy groups at you right from the start.

Head forward from the entrance and you will encounter your first group of Lancer bots. These are enemies you have seen before, but in Sector 3 they start appearing in larger packs. Use your Critical Shot ability to thin them out quickly. If you picked up the Photon Laser upgrade from Sector 2, this is a great time to use it for crowd control.

Continue through the main corridor. You will pass a Red Zone on your left. Red Zones are hazardous areas that drain your health if you stay in them too long, but they often contain valuable loot. We will cover the Red Zone loot in the collectibles section below.

Proceed through the door at the end of the corridor. This triggers a short cutscene where Diana comments on the vegetation. After the cutscene, you are in the main entrance hall. This is where the Terra Dome opens up, and navigation becomes less linear.

Terra Dome Entrance Safe Boxes and Collectibles

The Terra Dome Entrance contains several collectibles that are easy to miss if you are rushing through. Here is every item in Block 01 and exactly where to find it.

Safe Box 1: Before you go through the door to the interior of the dome, look to the left side of the corridor. There is a small alcove near some broken equipment. The first Safe Box is sitting there, partially hidden behind vegetation. Open it for Upgrade Components and a Mod.

REM (Read Earth Memory) 1: After entering the main hall, look for a set of stairs leading down on the right side. At the bottom, behind a Holo-Wall that you can hack open, you will find the first REM of Sector 3. This REM contains lore about the original Terra Dome construction.

Pure Lunum Deposit 1: In the Red Zone we mentioned earlier, along the left wall. You need to dash in, grab it, and dash out before the radiation drains too much health. If you have a radiation shield Mod equipped, now is the time to use it.

Mini Cabin Figure 1: On a shelf in the entrance hall, near the broken vending machine. This is one of those collectibles that players frequently miss because it blends into the environment. Walk up to the shelf and interact to collect it.

Gen Chip 1: Behind the Holo-Wall near the REM location. After you hack the wall open, check the small room to the right. The Gen Chip is on a terminal. This chip upgrades your hacking range, which will be useful throughout the rest of the sector.

Many players on the Pragmata subreddit report missing that first Mini Cabin Figure because it is positioned at an awkward camera angle. Walk slowly through the entrance hall and check every shelf and surface.

Enemies and Combat Tips for the Entrance

The Terra Dome Entrance introduces two new enemy types alongside returning ones. Here is what you will face and how to deal with each.

Lancers: These fast melee enemies return from earlier sectors. In Sector 3, they hit harder and dodge more aggressively. The best counter is a Sticky Bomb to the face followed by a Critical Shot while they are staggered.

Crushers: Heavy enemies with powerful ground-slam attacks. Their weak point is the glowing core on their back. Use Fast Move to get behind them, then unload. If you have the Pulse Carbine by now, its charged shot staggers Crushers reliably.

Impeders: New to Sector 3, these shield-bearing enemies block frontal attacks. You need to either hack their shields (which drops them temporarily) or flank them. Hacking is the faster option if your hacking range has been upgraded with the Gen Chip from this block.

Creeper Bots: The most frustrating new enemy. Creepers are nearly invisible until they are right on top of you. Listen for a faint electrical buzzing sound, which is your warning. When you hear it, dodge immediately and scan the area. A charged shot from any weapon reveals their position briefly. Forum players consistently rank Creepers as the most annoying enemy in Sector 3 due to their cheap damage output.

For mixed groups, I recommend taking out Impeders first (hack their shields, then shoot), followed by Creepers (listen for the audio cue), then Lancers, and saving Crushers for last since they are slow and predictable.

Eco Modeling Lab Walkthrough (Block 02)

Navigating the Eco Modeling Lab

The Eco Modeling Lab is where many players first get lost in Sector 3. Unlike the relatively linear Entrance, the Lab has multiple floors, interconnected corridors, and several Holo-Walls that hide entire rooms. The layout can feel like a maze if you are not paying attention to the environmental clues.

When you enter the Lab from the Center Hall, go straight ahead to find the main terminal. This terminal gives you a map of the Lab, which is extremely helpful. Activate it immediately. Without the map, navigating this area is significantly harder because many of the corridors look similar.

The Lab is organized around a central atrium with three floors. The ground floor contains the entrance and a few side rooms. The second floor is accessible via stairs on the east side. The third floor requires you to use a combination of hacking and platforming to reach. Each floor has its own set of collectibles and enemy encounters.

Here is a general navigation strategy that worked well for me. Clear the ground floor first, collecting everything you can find. Then head to the second floor and do the same. Save the third floor for last, as it has the hardest combat encounters in this block. This approach ensures you are adequately leveled and equipped before taking on the tougher fights.

Pay attention to the color-coded pipes running along the walls. Blue pipes lead to research areas, green pipes lead to the plant cultivation zones, and yellow pipes lead to maintenance corridors where many of the hidden collectibles are located. Following the yellow pipes is a reliable strategy for finding hidden rooms.

Gen Chip and REM Locations in Eco Modeling Lab

The Eco Modeling Lab has the highest concentration of collectibles in any single block of Sector 3. Here is where to find everything.

Gen Chip 2: On the ground floor, in the northwest research room. You need to hack a terminal to open the door. The Gen Chip is on a desk inside. This chip increases your hacking speed, which makes dealing with Impeders much easier.

Gen Chip 3: Second floor, behind a Holo-Wall in the east corridor. The Holo-Wall requires a level 2 hack, which you should have by now. The chip upgrades your Critical Shot damage.

REM 2: Ground floor, in the small office tucked behind the main terminal. The door is locked, and you need to find the access code. The code is on a note attached to a whiteboard in the adjacent room. The REM contains data about the ecosystem modeling process and hints at what happened to the researchers.

REM 3: Second floor, in the cultivation zone. After clearing the enemies in this area, look for a breakable vent cover on the north wall. Shoot it open and crawl through. The REM is at the end of the short vent passage.

Safe Box 2: Third floor, in the main control room. This room is guarded by two Crushers and a group of Lancers. Clear them out first, then open the Safe Box for a rare Mod and Pure Lunum.

Safe Box 3: Maintenance corridor (follow the yellow pipes from the second floor). The corridor has a Red Zone section, so plan your route carefully. The Safe Box contains a Firmware Updater and Upgrade Components.

Pure Lunum Deposit 2: Behind a breakable wall on the second floor. Look for cracks in the wall near the stairwell. Use a Sticky Bomb to blow it open. The Lunum deposit is inside.

Mini Cabin Figure 2: This is the one that most players miss. On the ground floor, in the southeast corner of the atrium, there is a small plant arrangement on a desk. The Mini Cabin Figure is nestled between the plants. It is very easy to walk right past it.

Players on the Pragmata subreddit frequently report missing the first Mini Cabin Figure in the Eco Modeling Lab. The trick is to check every desk, shelf, and plant arrangement thoroughly. These figures are small and designed to blend into the environment.

Eco Modeling Lab Challenge Rooms

The Lab contains two challenge rooms that test your combat and hacking skills. These are optional but highly recommended because they reward you with rare items.

Challenge Room 1 – Combat Trial: Located on the second floor, behind a door marked with a red symbol. This room locks you in and spawns waves of enemies. Wave 1 is three Lancers and two Impeders. Wave 2 adds a Crusher. Wave 3 is the hardest, with two Crushers and four Lancers coming at you simultaneously.

The key to this challenge room is crowd control. Use Sticky Bombs to group enemies together, then hit them with a charged Pulse Carbine shot. For Wave 3, focus on one Crusher at a time while using Fast Move to avoid the Lancers. The reward is a rare weapon Mod that increases Sticky Bomb blast radius.

Challenge Room 2 – Hacking Trial: On the third floor, this room contains a series of hacking puzzles that must be completed under a time limit. The puzzles involve manipulating a matrix of nodes to connect circuits. You get 90 seconds to complete all three puzzles.

For the hacking trial, I recommend equipping your hacking speed Gen Chip if you found it earlier in this block. The puzzles start simple but the third one has a complex layout. Focus on connecting the outer nodes first, then fill in the center. The reward is a Training Data file and a Gen Chip that extends your hacking range even further.

Both challenge rooms are worth completing. The combat trial teaches you enemy management skills that are essential for the boss fight later, and the hacking trial rewards you with upgrades that make the rest of the sector easier.

Plant Factory and Center Hall (Block 03)

Rebooting the Lim Regulators: Plant Factory

The Plant Factory is where Sector 3 starts to feel like a proper gauntlet. Your objective here is to reboot two Lim Regulators, which are large devices that control the terraforming systems. Each Lim Regulator is guarded by enemies and requires a hacking sequence to reboot.

Enter the Plant Factory from the Center Hall. The first room is a large open space filled with industrial equipment and plant growth. Take out the initial wave of Lancers, then look for the first Lim Regulator on the east side of the room. It is a tall, cylindrical device with glowing panels.

Approach the Lim Regulator and initiate the hacking sequence. You need to complete a matrix puzzle while enemies spawn around you. This is one of those moments where combat and hacking skills are tested simultaneously. My strategy is to start the hack, get one or two nodes connected, then deal with the enemies before continuing. Rushing the hack while enemies are attacking usually ends badly.

After rebooting the first Lim Regulator, a door opens on the north side of the room. Go through it and you will enter a corridor filled with Creeper bots. This is the section that players on forums consistently cite as frustrating. Move slowly through the corridor and listen for the audio cues. When you hear buzzing, stop and scan before proceeding. Use charged shots to reveal Creepers before they get close.

The second Lim Regulator is at the end of this corridor, in a room with two Crushers. Clear the Crushers first, then hack the Lim Regulator. This hacking puzzle is more complex than the first one, but there are no enemy interruptions since you cleared the room already. Take your time and solve it methodically.

With both Lim Regulators rebooted, the plant growth systems come back online. This opens new pathways in the Center Hall and gives you access to previously unreachable areas. Head back to the Center Hall to continue.

Center Hall Upper Floor Collectibles

The Center Hall serves as the hub for Sector 3, connecting all the other blocks. After rebooting the Lim Regulators in the Plant Factory, the upper floor of the Center Hall becomes accessible.

Safe Box 4: On the upper floor walkway, near the door to the Eco Modeling Lab. You can only reach this after the Lim Regulators are rebooted because the elevator to the upper floor was not functional before.

Pure Lunum Deposit 3: In the small alcove on the upper floor, accessible by dropping down from the walkway near the Plant Factory door. This is a tricky platforming section. Line up your jump carefully and use Fast Move to reach the alcove.

REM 4: Behind a Holo-Wall on the upper floor, near the railing overlooking the main hall. Hack the wall and enter the small maintenance closet. The REM is on a shelf along with some Upgrade Components.

The Center Hall also has a Training Simulation terminal on the upper floor. These simulations are combat scenarios that reward you with Training Data, Mods, and Upgrade Components. I highly recommend completing the available simulations before moving on to Soil Research, as the rewards will help with the tougher enemies ahead.

Training Simulations in Sector 3 focus on teaching you advanced techniques like combo attacks between Hugh and Diana, efficient use of the Overdrive Protocol, and dealing with mixed enemy groups. Each simulation takes about five minutes and the rewards scale with your performance. Getting an S-rank on the harder simulations gives rare Mods that are worth the effort.

Rescuing Eight in Sector 3

About midway through Sector 3, you will encounter Eight. This is a significant story moment that I will discuss without spoiling the major plot details.

After completing the Plant Factory and returning to the Center Hall, a cutscene triggers where Diana detects a life signal. Follow the signal through the upper floor corridors until you reach a locked chamber. Hack the door to open it, and you will find Eight inside.

Eight becomes a companion character for the remainder of Sector 3 and brings new abilities to your toolkit. Eight can manipulate Lunafilament, a resource found throughout the Terra Dome, to create bridges and platforms. This ability opens up new areas in previously visited blocks, so backtrack to earlier locations if you want to find everything.

The rescue sequence itself is straightforward. There are a few enemy encounters in the corridors leading to Eight’s chamber, but nothing you have not handled by this point. The main challenge is the navigation, as the corridors twist and turn with several dead ends.

Once Eight joins your party, you gain access to the Lunafilament ability. Practice using it in the Center Hall before heading to Soil Research. The ability requires you to target specific anchor points in the environment and then activate them. It takes some getting used to, but it becomes second nature after a few minutes.

With Eight in your party, revisit the Terra Dome Entrance and Eco Modeling Lab to reach areas that were previously inaccessible. There are additional collectibles hidden behind Lunafilament puzzles in both locations. This backtracking is necessary for 100% completion.

Soil Research Walkthrough (Block 04)

Soil Research Navigation and Terminals

Soil Research is the longest and most complex block in Sector 3. It features dark, atmospheric corridors, multiple terminal hacking puzzles, and some of the toughest enemy encounters in the entire sector. Players on forums praise the atmosphere but criticize the navigation difficulty.

Enter Soil Research from the Center Hall. The initial corridor is dark, with only your suit’s flashlight illuminating the path. This darkness is not just for atmosphere. It hides Creeper bots and makes navigation challenging. Move slowly and keep your ears open for audio cues.

The Soil Research block is organized around a series of research terminals that you need to activate to progress. Each terminal requires a hacking puzzle to unlock, and activating all terminals opens the path to the Terrarium and the Garden Keeper boss fight.

Terminal 1: Straight ahead from the entrance. The hacking puzzle is straightforward. Activating this terminal turns on emergency lighting in the first section, making navigation easier.

Terminal 2: In the east wing of the research area. To reach it, you need to use Eight’s Lunafilament ability to create a bridge across a collapsed floor section. The terminal itself has a moderate hacking puzzle.

Terminal 3: In the west wing, behind a locked door. The keycard for this door is in a side room on the east side of the first section. Look for a small office with a broken window. The keycard is on the desk. Terminal 3’s hacking puzzle is the most complex one in Sector 3, with multiple interconnected nodes. Take your time and work from the outside in.

Terminal 4: In the lower level of the research area. Access it via the freight elevator in the main chamber. This elevator only works after Terminals 1 through 3 are activated. Terminal 4 has a signal jammer nearby that interrupts your hacking. Destroy the signal jammer first, then hack the terminal.

Signal jammers are a new obstacle in Soil Research. These small devices emit a field that prevents hacking within their radius. They are usually hidden in corners or behind equipment. Look for a faint red glow to spot them. Destroy them with a quick shot before attempting any hacks in the area.

Soil Research Safe Boxes and Hidden Items

Soil Research has more collectibles than any other block in Sector 3. Many of these are hidden in dark corners or behind environmental puzzles, so thorough exploration is essential.

Safe Box 5: In the first section, behind a stack of crates on the south wall. Move the crates using Eight’s Lunafilament ability. The Safe Box contains a weapon slot upgrade and Pure Lunum.

Safe Box 6: East wing, in a small office accessible through a vent. Shoot the vent cover open and crawl through. The Safe Box has a rare Mod that increases your resistance to Red Zone damage. Given how many Red Zones are in Soil Research, this Mod is extremely valuable.

Safe Box 7: West wing, behind a Holo-Wall in the northwest corner. The Holo-Wall requires a level 3 hack. Inside the hidden room, you will find the Safe Box along with an Escape Hatch that provides a shortcut back to the Center Hall.

REM 5: Lower level, in the server room adjacent to Terminal 4. The server room door is locked, but you can hack it after destroying the signal jammer nearby. The REM contains research logs that reveal more about the Terra Dome project and the incident that caused the researchers to evacuate.

REM 6: In a hidden room behind a Lunafilament puzzle in the east wing. Use Eight’s ability on the anchor points to create a series of platforms leading to an upper alcove. The REM is there along with a Mini Cabin Figure.

Pure Lunum Deposit 4: In a Red Zone in the lower level. The Red Zone is near the freight elevator. Dash in, collect the Lunum, and dash out quickly. With the Red Zone resistance Mod from Safe Box 6, you can survive longer in the hazard.

Gen Chip 4: In the main chamber, on a high ledge accessible only via Lunafilament platforming. This is one of the trickiest platforming sections in the game. Create platforms using the anchor points on the walls and carefully make your way up. The Gen Chip increases your Overdrive Protocol duration, which is incredibly useful for the boss fight coming up.

Mini Cabin Figure 3: In the west wing, on a table in the office where you find the keycard for Terminal 3. It is easy to grab this one while you are already in the room for the keycard, but many players miss it because they pick up the keycard and immediately leave.

The Escape Hatch behind Safe Box 7 is worth finding even if you do not need the Safe Box contents. It provides a direct shortcut back to the Center Hall, which saves significant time if you need to backtrack for any reason, such as restocking at the Shelter or completing Training Simulations.

Garden Keeper Boss Fight Strategy (2026)

The Garden Keeper is the boss of Sector 3 and one of the tougher fights in Pragmata. This massive robot guards the Terrarium, the final area of the Terra Dome, and it has a moveset that punishes both aggressive and passive play styles. Players on forums consistently report that the Garden Keeper is harder than expected, primarily due to its lightning mechanics.

Phase 1 (100% – 60% Health): The Garden Keeper starts with sweeping arm attacks and ground slams. It also periodically charges across the arena. During this phase, the boss telegraphs its attacks clearly. Dodge the arm swipes by moving perpendicular to the swing direction. For ground slams, wait for the boss to raise both arms, then dodge backward twice.

The key damage window in Phase 1 is after the charge attack. When the Garden Keeper charges and misses, it slams into the wall and is staggered for about four seconds. Use this window to land a Critical Shot on the glowing core on its back. Repeat this cycle three or four times to push the boss into Phase 2.

Sticky Bombs are effective in Phase 1 because you can stick them to the boss during the stagger window. Plant two Sticky Bombs on the core, then detonate them with a shot for massive damage. With the blast radius Mod from the Eco Modeling Lab challenge room, this strategy is even more effective.

Phase 2 (60% – 25% Health): The Garden Keeper gains lightning attacks in Phase 2. It summons lightning strikes in marked areas of the arena, which are indicated by glowing circles on the ground. Get out of these circles immediately when they appear. The lightning strikes have a brief delay between the circle appearing and the strike landing, giving you about two seconds to move.

The boss also starts using a spinning attack that covers most of the arena. When you see the Garden Keeper raise both arms and start spinning, run to the outer edge of the arena and use Fast Move to dodge the final swing. After the spin, the boss is briefly vulnerable.

In Phase 2, the stagger window after the charge attack is shorter. You can still exploit it, but you need to be faster with your damage. I recommend using the Overdrive Protocol during these windows if you have the extended duration Gen Chip from Soil Research. Overdrive slows time, giving you more time to land your Critical Shots.

Watch out for the boss’s new combo in Phase 2, where it does a ground slam followed immediately by a lightning strike in the same area. If you dodge the slam and then stand still to attack, the lightning will catch you. Always reposition after dodging.

Phase 3 (25% – 0% Health): The Garden Keeper becomes enraged in Phase 3. It moves faster, attacks more frequently, and summons adds in the form of Lancer bots. The lightning strikes also become more frequent, with multiple circles appearing at once.

Your priority in Phase 3 is add management. When Lancers spawn, take them out quickly with the Pulse Carbine. Do not let them accumulate, because they will distract you from dodging the boss attacks. After clearing the Lancers, focus damage on the boss during any opening.

The best strategy for Phase 3 is to save your Overdrive Protocol for the final push. When the boss is below 25% health and you have Overdrive available, activate it and go all-out on offense. Use Sticky Bombs, Critical Shots, and charged Pulse Carbine shots. With the Overdrive duration extension from the Gen Chip, you should be able to deal enough damage to finish the fight before the boss can recover.

Remember to use Eight’s Lunafilament ability during the fight. There are anchor points in the arena that let you create barriers. These barriers block the boss’s charge attack and can buy you time to heal or reposition. Not many players realize this trick, and it can be the difference between winning and losing on your first attempt.

After defeating the Garden Keeper, you gain access to the Terrarium and can continue the story. The boss drops a significant amount of Pure Lunum and a unique Mod that enhances all of Hugh’s weapon capabilities. Pick up everything before moving on.
