The J-Lab Cards in Escape From Duckov are key progression items used to access restricted laboratory zones scattered across Duckov’s outskirts. While the first entry card is fairly easy to find, the advanced versions — including Level 2 and the colored access cards (Red, Blue, Green, and Purple) — are much rarer, often hidden behind exploration, loot rotations, and quest unlocks.
This guide explains how to find every J-Lab Card, their confirmed spawn zones, and the best farming routes to make your lab raids efficient and repeatable.
What Are J-Lab Cards?
J-Lab Cards act as security clearance passes used to enter the underground research complexes located around the Duckov region. Each card tier grants access to deeper lab sectors or color-coded containment areas tied to endgame loot and experimental gear.
Here’s what to expect from each type:
- J-Lab 1 Card – Base level access (entry to standard lab zones)
- J-Lab 2 Card – Intermediate clearance (lower B1 levels)
- Color Cards (Red, Blue, Green, Purple) – Advanced and optional keys unlocking sealed wings or hidden experimental areas
Unlike typical key items, these cards are consumable and non-permanent, meaning each raid or entry attempt costs one card.
J-Lab 1 Card – Basic Entry Access
How to Get It
There are two main ways to obtain your first J-Lab 1 Card in Escape From Duckov:
- Hidden Mine (Farm Town Region)
- Search the Hidden Mine, located near Farm Town, for card spawns.
- The card can appear in corners, near mining equipment, or against walls.
- Cards seem to respawn roughly every 4–5 in-game cycles, making this the best early-game farming method.
- Purchasable After Quest: “Copy Pass”
- Complete the side quest “Copy Pass” to unlock the merchant Xiaoming.
- Once done, you can purchase J-Lab 1 Cards from Xiaoming’s shop for a fixed price.
- This is the safest way to restock if you frequently raid labs or burn through passes.
Purpose
- Unlocks the J-Lab entry gate and initiates your first official lab infiltration.
- Necessary to complete several early progression objectives tied to story advancement and loot milestones.
J-Lab 2 Card – Deeper Lab Access (B1 Level)
Where to Find It
- Labs B1 – Wanderer Drops
- Wanderers inside the B1 floor of the J-Lab complex occasionally drop Level 2 Cards.
- The drop rate is quite low, but consistent lab farming increases your odds.
- Executive Office Room Spawns
- Some players report finding Level 2 Cards inside office-type rooms on the first floor of the lab.
- Look on desks, metal shelving, or computer terminals.
- These spawns aren’t guaranteed but seem to reappear after resets or raids.
Tips
- Focus your farming runs on Wanderer patrol zones; they have the highest reported drop rate.
- Restarting a raid or switching servers can refresh spawn tables and improve chances.
Color Access Cards (Red, Blue, Green, Purple)
Colored J-Lab Cards serve as special access keys for experimental or sealed sectors within the Duckov lab network. These areas usually contain rare weapon blueprints, unique lore terminals, and high-grade loot containers.
They are not tied to the main story, which means you’ll need to explore and search carefully.
Green Card
Location: Found in a house within Farm Town.
Details: There’s a note left inside the same house that hints at the card’s whereabouts.
Spawn Behavior: May spawn randomly on tables or near cabinets. The house location seems to shift across different world seeds.
Pro Tip: Check any houses with visible research notes or scattered paper debris — they often indicate a card spawn.
Purple Card
Location: House near the Farm Town Sawmill.
Details: Frequently spawns inside or near the sawmill’s worker housing.
Spawn Cycle: Not consistent; may appear after world resets or several in-game days.
Player Tip: One confirmed spawn was on a metal shelf inside the second building closest to the sawmill fence.
Red Card
Current Status: Unconfirmed fixed spawn.
Speculation: Believed to drop during Executive Wing runs or advanced sealed chamber raids in later lab floors.
- Possible Methods:
- Defeating elite Wanderers.
- Completing high-tier challenge contracts.
- Looting secured office vaults in Labs B2.
Blue Card
Current Status: Unconfirmed.
Suspected Source: May be tied to questlines introduced post-raid progression, or deep storage rooms in advanced sectors.
Observation: Some players theorize the Blue Card grants access to environmental hazard labs, based on unreleased terminal data.
Farming and Progression Strategy
To maximize efficiency, follow this route:
Start at Farm Town → Hidden Mine
Farm repeatable J-Lab 1 Cards while collecting loot and supplies.
Keep at least 5–10 passes before progressing deeper.
Complete “Copy Pass” Quest
Unlock Xiaoming’s store for sustainable restocks.
Run J-Lab B1 Repeatedly
Focus on enemy drops to get J-Lab 2 Cards.
Each clear increases your odds for rare drops.
Revisit Farm Town Houses Between Cycles
Check sawmill and housing structures for Green and Purple Cards.
Mark confirmed spawns manually for easy tracking later.
Save Advanced Cards
Use color cards only after verifying the corresponding sealed doors.
These are often one-time-use, so plan your exploration carefully.
Collecting all J-Lab Cards in Escape From Duckov is a blend of persistence and exploration. While the base entry pass can be easily restocked, the colored and deeper-level cards are intentionally designed to reward players who dive deep into Duckov’s world — searching every corner, raiding every bunker, and piecing together scattered lore clues.
If you’re hunting for 100% completion, make Farm Town your home base and regularly rotate between the Hidden Mine, Sawmill, and Lab B1 runs. Every cycle increases your odds of finding the rare color cards and progressing toward full lab access.
