In Pragmata, secret walls (also called holo-walls, hollow walls, or illusory walls) hide valuable loot such as safe boxes, Read Earth Memories (REMs), mods, upgrade components, Pure Lunum, and cabin coins. There are two main types: holo-walls (illusory flat panels) and crystal barriers (blue or red filament masses/spikes). Most require story progression or specific abilities to access, encouraging backtracking.
This guide explains the different secret wall types, how to reveal and unlock them, the key abilities needed, and pro tips for finding every hidden area.
Types of Secret Walls in Pragmata
- Holo-Walls (Hollow/Illusory Walls): These appear as large, flat gray or white panels with a subtle blue holographic shimmer. They look like normal walls until you get close. Behind them are hidden rooms with enemies, safe boxes, or collectibles.
- Crystal Barriers (Filament Masses or Spikes): Glowing blue or red crystal/rock walls that block paths. These are more obvious but cannot be destroyed until you unlock the right ability. They often hide shortcuts, combat arenas, or high-value caches.
Note: Some glowing alien debris walls require even later abilities (like Cleanse in Sector 5) to clear.
How to Unlock and Use the Lim Eraser (For Crystal Barriers)
The Lim Eraser is the main ability for destroying blue crystal barriers and red spikes. You get it automatically as part of the main story:
- Complete Sector 1 (Solar Power Plant) and defeat the SectorGuard boss.
- Progress through Sector 2: Mass Production Array (the city-like area with beacons and the Business District).
- Reach the Lim Recycling Facility (near the end, after handling lasers and minor enemies).
- Drop down past the red lasers, enter the lab at the bottom, and interact with the tall white terminal/device.
- Diana absorbs the data (she bites the chip), unlocking the Lim Eraser permanently.
How to Use Lim Eraser:
- Approach a blue crystal barrier or red spike wall.
- Hold E (keyboard) or L1/LB (controller) to charge and release a blast.
- The wall shatters, revealing the hidden area. Watch for enemies inside!
This ability lets you revisit earlier sectors (like Sector 1) to open previously blocked paths and collect missed loot.
How to Find and Reveal Holo-Walls
Holo-walls are trickier because they don’t glow until you’re right in front of them:
- Visual Cue: Look for plain gray/white walls with a faint blue holographic shimmer when close. They are always flat panels.
- Best Detection Method: After unlocking Sector 3 (Terra Dome), purchase the Object Scan ability at the Unit Printer in the Shelter (costs a small amount of Pure Lunum or Lunafilament).
- Activate Object Scan (usually the Square/X/Y button) while exploring.
- It pings nearby hidden items—if an item shows up but you can’t see it, a holo-wall is almost always nearby hiding it.
- Walk directly into suspicious flat walls—they fade away when you approach or interact.
Every holo-wall in the game has at least one scannable item behind it (safe boxes, REMs, etc.), so the scanner makes 100% exploration much easier.
Smart Strategies for Finding All Secret Walls
- Backtrack Often: Many holowalls and crystal barriers appear in early sectors but open only after getting the Lim Eraser or Object Scan. Return to Sector 1 and Sector 2 after story milestones.
- Explore Thoroughly: Check corners, dead-end hallways, behind crates, upper platforms, and areas with lasers or mannequins. Turn around frequently after dropping down or using ziplines.
- Combine with Object Scan: Ping constantly in new or revisited areas. Missing collectibles are often behind illusory walls or just out of bounds.
- Clear Red Zones and Training Sims: These sometimes unlock new shelter upgrades or give hints toward hidden areas.
- Listen and Look: Subtle audio cues or enemy spawns can indicate a hidden room. Holo-walls often lead to enclosed arenas with extra enemies and rewards.
Pro Tip: Don’t stress about secret walls in Sector 1 until you have Object Scan and Lim Eraser—you’ll naturally find most on a second pass.
Rewards Behind Secret Walls
Hidden areas commonly contain:
- Safe Boxes (Lunafilament, Cabin Coins, Pure Lunum)
- Read Earth Memories (for Cabin Coins and Diana interactions)
- Mods and hacking nodes
- Upgrade components
- Shortcuts or new paths
Clearing them boosts your build significantly and helps with trophies like “Wall? What Wall?” (find your first holo-wall).
Later Abilities for Tougher Barriers
- Cleanse Ability (unlocked in Sector 5 after the Lunum Mines): Clears remaining glowing alien debris or red goo walls.
- Continue progressing the story to unlock even more backtracking opportunities.
If you’re stuck on a specific sector (e.g., finding a holowall in the Mass Production Array or a crystal in the Solar Power Plant) or need exact locations for a particular collectible, provide more details for targeted help!
Mastering Pragmata’s secret walls turns the Lunar Cradle into a rewarding exploration playground. Combine object scan, Lim eraser, and careful backtracking to find every hidden cache and maximize your upgrades. Happy hunting on the Moon!
