Pragmata Walkthrough: Sector 3 Terra Dome Guide (June 2026)

Sector 3 in Pragmata drops you into the Terra Dome, and honestly, it is one of the longest and most involved sectors in the entire game. Between the winding corridors, hidden collectibles, and that brutal Garden Keeper boss fight at the end, you are in for a serious test of everything you have learned so far. I spent hours mapping out every Safe Box, Pure Lunum shard, and Read Earth Memory in this sector so you do not have to waste time backtracking.

This Pragmata Walkthrough Sector 3 Terra Dome guide covers the complete progression from your first steps at the Terra Dome Entrance through the Plant Factory, Eco Modeling Lab, Soil Research, and finally the Garden Keeper boss fight. I will walk you through every area step by step, point out every collectible location, and share the strategies that actually work against the toughest enemies in this zone.

Pragmata is a sci-fi action shooter from Capcom set on the moon, where you play as the astronaut Hug alongside the android Diana. Together you fight through robot-infested sectors, hack security systems, and collect data to push back against the rogue AI antagonist IDUS. Sector 3 is where the stakes get real and the paths get complicated, so let me help you get through it clean.

Terra Dome Entrance — Getting Started

The moment you arrive at the Terra Dome Entrance, you will notice the atmosphere shift. The lunar greenery spilling through cracked dome panels is a stark contrast to the cold corridors you left behind in Sector 2. Take a moment to orient yourself before pushing forward because the paths here branch quickly and it is easy to miss items on your first pass.

Head forward from the arrival point and you will encounter your first Red Zone of this sector almost immediately. The Red Zone is a contaminated area that deals constant damage to Diana if you do not clear the corruption fast enough. Use your Lim Eraser to neutralize the corruption nodes as you push through. There are three nodes in this first Red Zone: one on the left wall behind some plant overgrowth, one straight ahead near a collapsed pillar, and one on the elevated platform to your right. Clear all three to disable the zone.

Before you go through the door leading to the Terra Dome interior, look to the right of the entrance. Tucked behind a cluster of lunar ferns is the first Safe Box of Sector 3. This one contains a Mini Cabin Figure collectible, which counts toward your overall Terra Dome completion percentage. If you walk past this without grabbing it, you will need to backtrack later since fast travel does not unlock until you reach the Central Lift.

First Enemy Encounters

The Terra Dome Entrance throws Lancers and Watchers at you right away. Lancers charge in with rapid melee strikes, so keep your distance and use the Pulse Carbine to stagger them before they close the gap. Watchers hover overhead and fire tracking projectiles. The trick with Watchers is to wait for their red targeting laser to lock on, dodge sideways at the last second, and then return fire while they are recharging. Two Pulse Carbine bursts will take down a standard Watcher.

After clearing the enemies, follow the corridor to the left to find a Read Earth Memory sitting on a bench near a shattered window. This REM gives you lore about the Terra Dome’s original purpose as an agricultural research facility. Continue forward and you will reach the Plant Factory door. The transition is marked by a short loading sequence, so make sure you have your weapons and mods equipped the way you want before triggering it.

Rebooting the Lim Regulators — Plant Factory

The Plant Factory is where the Terra Dome sector really starts to open up. Your primary objective here is rebooting the Lim Regulators to restore environmental control to the dome, but there are plenty of collectibles and side paths to explore along the way. I recommend clearing this area fully before moving on because several of the items you find here will make the later boss fight much more manageable.

When you enter the Plant Factory, go straight ahead to the main processing floor. You will see two Lim Regulators marked on your HUD, but they are both blocked by corruption fields. Before dealing with either one, head to the northwest corner of the room where you will find a Safe Box containing a Gen Chip. This Gen Chip upgrades Diana’s hacking range, which is incredibly useful for the rest of the sector.

Signal Jammer Mechanics Explained

The Plant Factory introduces signal jammers for the first time in Sector 3. These devices prevent Diana from hacking nearby terminals and enemies until they are destroyed. Signal jammers appear as small black boxes with pulsing red lights, usually mounted on walls or ceilings. You need to shoot them directly to disable them. They are often hidden behind obstacles or placed in elevated positions that require thruster-boosted jumps to get a clear angle.

There are two signal jammers in the Plant Factory. The first is on the ceiling above the left Lim Regulator. Jump up to the catwalk and you can shoot it from above. The second is behind a destructible wall near the eastern corridor. Use Sticky Bombs on the cracked wall panel to blast it open and then destroy the jammer inside. Once both jammers are down, you can freely hack the Lim Regulators and any security terminals in the area.

Challenge Rooms — Area A vs Area B

After rebooting the first Lim Regulator, a door opens leading to two challenge rooms labeled Area A and Area B. You only need to complete one to progress, but completionists will want to clear both. Here is the breakdown of each choice:

Area A is a combat gauntlet. Waves of Crushers and Impeders spawn in a confined space. The Crushers are slow but hit extremely hard, while Impeders create shield barriers that protect other enemies. My recommendation: equip the Cheap Shot mod on your Pulse Carbine to stagger Crushers quickly, then focus on the Impeders first to remove the shields. Area A rewards you with a Pure Lunum and an Upgrade Component when cleared.

Area B is a platforming and puzzle challenge. You need to navigate floating platforms while hacking security nodes in sequence. The time limit is tight, and falling means starting over. Use thrusters to cover the larger gaps and hack nodes in this order: left, center, right. Area B rewards you with a Training Data and a different Upgrade Component. Both areas are worth completing, but if you are short on time, Area A gives better rewards for the upcoming boss fight.

Remaining Plant Factory Collectibles

Before leaving the Plant Factory, make sure you have grabbed these items. There is a Safe Box in the lower maintenance tunnel accessible through a vent near the second Lim Regulator. This box holds a REM about the Plant Factory’s original operators. There is also a Pure Lunum sitting on a shelf in the storage room behind the Area B door. Finally, check the catwalk above the main processing floor for a Cabin Coin tucked behind some piping.

Eco Modeling Lab — Gen Chip Puzzle Walkthrough

The Eco Modeling Lab is the most complex area in the Terra Dome sector, and the place where most players get stuck. Between the Gen Chip puzzles, invisible Creeper enemies, and branching paths, it is easy to lose your bearings. I am going to walk you through this area methodically so you do not miss anything.

When you first enter the Eco Modeling Lab, you will be in a large cylindrical room with multiple floors. The main objective here involves collecting three Gen Chips and inserting them into the central terminal to unlock the path forward. Each Gen Chip is locked behind a puzzle that requires specific hacking sequences.

Gen Chip Puzzle 1 — Ground Floor

The first Gen Chip is on the ground floor, locked inside a glass case. To open it, you need to hack three terminals in the correct sequence. The terminals are labeled with symbols: a leaf, a water drop, and a sun. Hack them in this exact order: water drop, leaf, sun. The correct sequence simulates the natural growth cycle and unlocks the case. Grab the Gen Chip and the Training Data sitting next to it.

The glass case room also contains a Safe Box in the back corner. This one holds a Precision Shot mod which increases headshot damage by 20 percent. This mod is absolutely worth equipping immediately because it will carry you through the rest of the sector and the Garden Keeper fight.

Gen Chip Puzzle 2 — Second Floor Catwalk

Take the elevator to the second floor. You will face Spiders and Bombers along the catwalk. Spiders are fast and attack in swarms, so use wide-range Sticky Bombs to clear groups. Bombers hover at range and throw explosive projectiles. Dodge the red targeting circles on the ground and return fire with the Pulse Carbine. Three headshots with the Precision Shot mod will drop a Bomber instantly.

The second Gen Chip puzzle involves redirecting energy beams through a series of relay nodes. There are four relay nodes in the room, and you need to rotate them so the beam path connects from the power source to the chip containment unit. Rotate node 1 twice, node 2 once, node 3 three times, and node 4 twice. The beam will connect and release the second Gen Chip. A Pure Lunum is also floating above the containment unit — use your thrusters to reach it.

Gen Chip Puzzle 3 — Third Floor and Invisible Creepers

The third floor is where things get rough. This area introduces Creeper bots, which are invisible enemies that stalk you through the corridors. You cannot see Creepers normally, but you can detect them by watching for subtle visual distortions in the air and listening for a faint electronic hum that gets louder as they approach. When you hear the hum getting close, dodge immediately and fire a Sticky Bomb at the distortion. The explosion will reveal the Creeper and stun it long enough to finish it off with your Pulse Carbine.

Having Diana scan periodically helps too. Her scan ability highlights nearby enemies including invisible ones for about three seconds. Use it every time you enter a new room on the third floor. There are four Creepers total on this floor, and they respawn if you leave and come back.

The third Gen Chip is in a sealed room at the end of the third floor corridor. To open it, you need to defeat all four Creepers and then hack the terminal that powers the door. Insert the Gen Chip into the central terminal and the Eco Modeling Lab is complete. Before leaving, check behind the collapsed shelves near the elevator for a Safe Box containing the Sticky Bombs weapon upgrade if you have not already picked it up.

Center Hall Upper Floor

After completing all three Gen Chip puzzles, return to the Center Hall and take the lift to the upper floor. Here you will find a REM on a desk and a Training Data near the viewport. There is also an escape hatch on this floor that serves as a shortcut back to the Terra Dome Entrance if you need to backtrack for missed collectibles. Make note of its location because the fast travel network connects through this hatch once activated.

Meeting Eight — Story Progression

After clearing the Eco Modeling Lab and the Center Hall upper floor, the story takes a significant turn. You will find Eight, a key character trapped in a containment cell deep within the Terra Dome’s research wing. The encounter is primarily story-driven, but there is a brief combat sequence as you approach the cell where a SectorGuard and two Lancers ambush you in a narrow corridor.

Focus on the SectorGuard first. It has a heavy shield that blocks frontal attacks, so use Diana’s hack to disable the shield from behind, then pour Pulse Carbine fire into its exposed back. Once the SectorGuard is down, the Lancers are straightforward to handle. After the fight, approach the containment cell and interact with the terminal to free Eight.

Eight is an AI consciousness that was captured by IDUS and held in the Terra Dome. Once freed, Eight provides you with critical data about the remaining sectors and the weaknesses in IDUS’s defenses. This data unlocks new hacking abilities for Diana and grants access to the Soil Research area. Eight also gives you the Recursive Learning mod, which increases experience gained from combat encounters for the rest of the game. Equip it immediately if you are working toward max level.

The meeting with Eight is relatively brief compared to the other sections, but do not skip the dialogue. The information Eight shares about the GeoScience Lab and the Terrarium foreshadows the challenges ahead and contains hints about optional paths you can take in Soil Research for extra collectibles.

Soil Research — Terminal Locations and Collectibles

Soil Research is the largest sub-area in the Terra Dome sector and the place where completionists will spend the most time. Between the GeoScience Lab terminals, the Soil Research safe boxes, and the weapon pickups scattered through the facility, there is a lot to track. I am going to list every terminal location and collectible in the order you encounter them so you can check items off as you go.

GeoScience Lab Terminals

The GeoScience Lab is the first section of Soil Research. You need to activate five research terminals to unlock the path to the Terrarium. Here are all five terminal locations:

Terminal 1: Enter the GeoScience Lab and go straight ahead. The first terminal is in the main analysis room on the central console. Hack it to activate.

Terminal 2: From Terminal 1, take the left corridor to the sample storage room. The terminal is on the far wall behind a row of sample containers. A Watcher guards this room, so clear it first.

Terminal 3: Return to the main room and take the right corridor. Terminal 3 is in the soil analysis chamber. You need to clear a Red Zone to reach it. There are two corruption nodes: one above the door frame and one under the analysis table.

Terminal 4: Take the stairs near Terminal 3 up to the observation deck. Terminal 4 is on the balcony overlooking the main room. A Safe Box is sitting right next to it containing a Pure Lunum. Grab both at the same time.

Terminal 5: The last terminal is in the server room at the back of the GeoScience Lab. To access it, destroy the signal jammer mounted on the ceiling (look for the pulsing red light) and then hack the security lock on the server room door. Inside you will find Terminal 5 along with a Training Data and a REM about the original soil experiments conducted on the moon.

Soil Research Safe Boxes and Collectibles

With the GeoScience Lab terminals activated, the Soil Research wing opens up. This area has some of the most valuable collectibles in the entire sector. Here is every item in the order I recommend collecting them:

First, head to the eastern greenhouse passage. A Safe Box is hidden behind a collapsible wall panel on the north side of the passage. Shoot the panel to reveal the box, which contains a Gen Chip. Next, continue through the greenhouse to find a Pure Lunum on top of a plant growth module. Use your thrusters to reach it.

In the central Soil Research hub, you will face a Walker MK-II enemy. This is a tougher variant of the Walker enemies you fought in earlier sectors. The Walker MK-II has heavy armor on its front and legs, but the cooling vents on its back are a critical weak point. Circle around it using thruster dashes and focus all your fire on the glowing blue vents. With the Precision Shot mod equipped, you can take it down in about 15 seconds if you land your shots consistently.

After the Walker MK-II fight, check the northwest office for a Safe Box holding the Photon Laser weapon. The Photon Laser fires a continuous beam that deals sustained damage and is exceptional for boss fights. Pick this up now because it is the best weapon for the Garden Keeper.

The remaining collectibles in Soil Research include another Safe Box in the lower excavation pit containing a Mini Cabin Figure, a Training Data near the Terrarium access terminal, and a Cabin Coin hidden behind the water purification tanks in the northeast corner.

Recommended Loadout for the Boss Fight

Before entering the Terrarium to face the Garden Keeper, I strongly recommend this weapon and mod setup. Your primary weapon should be the Photon Laser with the Precision Shot mod equipped. The sustained beam damage combined with the headshot bonus shreds the Garden Keeper’s health bars in every phase. Your secondary should be Sticky Bombs for crowd control during the adds phases. For your third slot, keep the Pulse Carbine with the Cheap Shot mod as a reliable fallback option. Make sure Diana has the Recursive Learning mod active so you earn maximum experience from the fight.

Garden Keeper Boss Fight Strategy

The Garden Keeper is the final boss of Sector 3 and one of the more demanding fights in Pragmata up to this point. It is a massive plant-machine hybrid that fills most of the Terrarium arena. The fight has three distinct phases, and each one demands a different approach. Here is how I beat it consistently.

Phase 1 — Root Network

When the fight begins, the Garden Keeper is rooted in the center of the arena with its core shielded. Four glowing root nodes are spread around the arena floor, and you need to destroy all four to expose the core. The root nodes regenerate after about 20 seconds if you do not destroy them all quickly enough, so move fast.

The Garden Keeper attacks with sweeping vine strikes during Phase 1. Watch for the ground shake animation before each strike and dodge perpendicular to the sweep direction. Run to each root node, fire a Sticky Bomb at it to deal burst damage, then immediately dodge the follow-up vine attack. Using the Photon Laser on root nodes works well too since the sustained beam destroys them in about three seconds of continuous fire.

Once all four root nodes are destroyed simultaneously, the Garden Keeper’s core opens and you have roughly eight seconds to deal maximum damage. Unload the Photon Laser directly into the glowing yellow core. With the Precision Shot mod, you can strip about 30 percent of the boss’s total health in this single damage window.

Phase 2 — Thorns and Adds

At 60 percent health, the Garden Keeper enters Phase 2. It uproots itself and becomes mobile, slowly crawling around the arena while firing thorn projectiles and spawning Spiders and Bombers. The key to this phase is managing the adds quickly so you can focus on the boss.

When adds spawn, immediately throw Sticky Bombs at the Spider clusters to clear them in one explosion. Pick off Bombers with your Pulse Carbine while continuing to circle the arena. Never stop moving during Phase 2 because the thorn projectiles track your position. The thorns move slowly enough that a constant circular strafe will keep you safe, but if you stop moving even briefly, they will catch up.

The Garden Keeper’s weak point in Phase 2 is the glowing mass on its underbelly. You need to get close and aim upward to hit it consistently. Use thruster dashes to close the distance, fire the Photon Laser into the underbelly for about four seconds, then dash away before the boss slams down with a ground-pound attack. The ground-pound has a huge area of effect, so put at least three dashes of distance between you and the boss when you see it rearing up.

Phase 3 — Desperate Bloom

At 25 percent health, the Garden Keeper enters its final phase. It plants itself in the center of the arena again and creates a massive energy shield around its body. You need to destroy three flower turrets mounted around the arena to disable the shield. The flower turrets fire rapid seed shots that are hard to dodge individually, so destroy them quickly.

Use Sticky Bombs on the two ground-level turrets and the Photon Laser on the elevated turret that requires a thruster jump to target. Once all three turrets are down, the shield drops and the core is exposed for the final time. Unload everything you have. The Photon Laser with Precision Shot mod is your best friend here because the core takes massively increased headshot damage in this final phase.

The Garden Keeper will try one last attack where it charges up a massive area-of-effect bloom explosion. You will see the arena floor start glowing green and a 10-second timer appears on the boss. If you deal enough damage to the core before the timer expires, you will stagger the boss and cancel the attack. If you do not deal enough damage, the explosion will likely kill you outright. Keep firing and do not panic. With the loadout I recommended, you should be able to finish the boss with about three seconds to spare.

After the Garden Keeper falls, you receive the Red Zone Key, a significant amount of experience from the Recursive Learning mod, and the Terra Dome sector is officially complete. The Central Lift activates, connecting all areas of the Terra Dome for fast travel and any cleanup you need to do.

Wrapping Up the Pragmata Walkthrough Sector 3 Terra Dome

Completing the Pragmata Walkthrough Sector 3 Terra Dome is a major milestone in the game. You have cleared the longest sector so far, freed the AI consciousness Eight, collected dozens of items, and taken down the Garden Keeper. The data Eight provides and the Red Zone Key you earned from the boss will open up new areas and abilities as you push into the next sectors.

If you are going for 100 percent completion, use the Central Lift fast travel to revisit any areas where you missed Safe Boxes, Pure Lunum, or REMs. The Terra Dome is much easier to explore once all enemies are cleared and all paths are unlocked. Take your time and grab everything because the collectibles from this sector contribute to global rewards that carry through the rest of the game.

The challenges in Sector 3 are a taste of what comes next. Every mechanic you mastered here — the Gen Chip puzzles, signal jammer destruction, Creeper detection, and boss phase management — shows up again in harder forms later. You are well prepared for whatever Pragmata throws at you next.
