Pure Lunum is Pragmata's premium currency. You spend it at the Unit Printer back at the Shelter to print weapon modules and top-tier loadout parts. Almost every Pure Lunum deposit sits inside a Red Zone, which means you need a Red Gate Key to reach it.
What They Are
A cluster of pale crystalline shards glowing faintly blue. They drop in chunks — a single pickup is worth roughly one Unit Printer transaction. Most Pure Lunum nodes live inside Red Zones, a hazard mode that opens when you slot a Red Gate Key into the zone's terminal. The zone fills with stronger enemies and a time-pressure fog; surviving long enough to grab the Lunum is the reward.
A handful of deposits sit in the open world and can be picked up on the first pass. The rest stay locked behind:
- Red Zones — need a Red Gate Key and a confident loadout
- Blue Lim barriers — unlock with the Lim Eraser
- Cleanse gates — unlock with the Cleanse ability late in Sector 5
Total Count
Around 17 Pure Lunum deposits across the playable sectors:
| Sector | Count |
|---|---|
| Sector 1 · Solar Power Plant | 1 |
| Sector 2 · Mass Production Array | 4 |
| Sector 3 · Terra Dome | 4 |
| Sector 4 · Lunum Mines | 2 |
| Sector 6 · Central Port | 6 |
Locations by Sector
Sector 1 · Solar Power Plant
- Power Distribution Center — one deposit behind a blue Lim barrier; return with the Lim Eraser after you finish Sector 2
Sector 2 · Mass Production Array
- Shopping District — two deposits (one rooftop, one gated by the first Red Zone in the district)
- Business District — two more, both sitting in Red Zones; you'll need two Red Gate Keys from this sector
Sector 3 · Terra Dome
- Terra Dome Entrance — one node in the greenhouse annex
- Eco Modeling Lab — two deposits, both requiring hack-terminal tree platforms to reach
- Soil Research Center — one, inside the invisible-enemy arena
Sector 4 · Lunum Mines
Only two deposits in Sector 4, which makes them easy sweeps:
- Warehouse — one at the back of the box-stacking room
- Main Excavation Site — one at the center of the pit
Sector 6 · Central Port
Sector 6 is the Pure Lunum goldmine — six deposits total, most behind Cleanse gates:
- Regolith Lab — three deposits spread across the sub-level
- Lunafilament Lab — three more, all gated by Cleanse and filament-cleaning puzzles
Tips
- Don't rush Red Zones early. A single Red Zone death drops you back with no rewards; carry full health stocks and a reliable hack setup before you slot the key.
- Hoard your first three Red Gate Keys. Save them for Sector 2 and Sector 3 deposits — the Unit Printer parts you unlock there carry you through the rest of the game.
- Cleanse gates = Sector 6 priority. Once you unlock Cleanse, go back to Lunafilament Lab first; three deposits in one run.
- Pure Lunum does not respawn. Each node is one-and-done per save. Use Unknown Signal for a full reset run if you want to re-farm for New Game Plus gear.
