Abiotic Factor Labs Progression: Inner Wing to Mycofields
Follow Labs checkpoints from the Inner Wing through the security reset to Mycofields, with Tier 3 access, Leyak Essence and Antethermite requirements.
Which Labs checkpoint are you on?
Start here after opening the route from the Manufacturing Synchrotron. Work through the Inner Wing checkpoints to reach Mycofields and open the Vacuum Chamber.
Table tip: On narrow screens, swipe sideways within the table to see all columns.
| Where you are stuck | Required action | Success check |
|---|---|---|
| Inner Wing bridge console | Use a Keypad Hacker (Tier 3) | The containment route opens |
| Helmholtz turret gap | Cross to the Furniture Store portal route | You reach the portal without crossing the firing lanes |
| Furniture Store | Find and press five buttons, then use its central elevator | Exit into the upper Labs route |
| X-ray barrier before Control Center | Supply four Leyak Essences | Barrier turns off |
| Security system | Reach and operate the reset control | Objective advances to finding Mycofields |
| Level 6 containment door | Use Tier 3 access | Mycofields entrance is accessible |
| Vacuum Chamber webbing | Use crafted Antethermite | Route into Security opens |
Enter the Inner Wing and reach the security reset
Prepare Tier 3 access
The Inner Wing console is on the bridge below the yellow-painted room. Use Tier 3, not Tier 2. This landmark is described in the Inner Wing access guide.
At a Crafting Bench, upgrade one Tier 2 Hacker + two Quantum Glass + one Memory Brick into Tier 3. A Memory Brick needs three Case Fans, two Military Electronics, one Projection Matrix and one Jailbroken CPU. Read both attachments of the “Optical Components” email for the two discoveries, or gather their components.
A Projection Matrix uses one Anteverse Gem, one Optic Lens, two Staplers and two Liquid Crystals. In Labs, use the Adjustment Wing exchangers for crystal materials; the Manufacturing trade chain covers the Optic Lens. Check the bench construction component table for Quantum Glass and Lab Burner recipes.
The Memory Brick’s Jailbroken CPU comes from defeating a Containment Bot; an ordinary Security Bot CPU is not a substitute. Reserve it for the Hacker upgrade before spending it elsewhere.
Through Helmholtz and the Furniture Store
From containment, follow the Helmholtz route on level 3. The historical walkthrough uses the yellow-marked entrance and wooden bridges across the broken walkway to avoid the live-fire lanes. Carry bridges, a light, healing supplies and a repaired weapon; do not assume armor makes turret fire safe.
Enter the Furniture Store portal. Find all five buttons before pressing the first if you want time to explore without the spawned horde. Search its three store floors; button positions change on re-entry. Press the buttons, return to the central elevator and ride up to the exit. Leaving and coming back resets this puzzle, so a fixed five-coordinate list would be misleading.
Back in upper Labs, enable the shortcut elevator before continuing to the X-ray barrier. This saves repeating the store route on the return trip.
Collect four Leyak Essences without a circular recipe
Inspect the X-ray emitter outside the Leyak cell in XR Containment to learn the X-Ray Tower. Its recipe is one Projection Matrix, two Refined Carbon, one Lab Burner and one Keyboard at a Crafting Bench. Place and power it, then let it expose a Leyak; the entity disappears and leaves Essence.
Reserve four Essences for the barrier. The portable X-Ray Lamp is optional, not a requirement for obtaining your first Essence. These items irradiate the carrier: use radiation protection and avoid carrying them through unrelated supply runs.
At the barrier, fill the four Flow Control Modules. In the 2024 corridor layout, follow the lower room’s right wall toward the lift, then use upper-floor cover to reach the corridor with bodies and stacked luggage beneath the reset control. Clear threats before moving to the control. Operate the reset and confirm the objective changes.
These corridor directions use the 2024 layout. If your room differs, navigate by the named control and active objective instead of following the turn directions.
Reach Mycofields and return with Anteverse Gel
After the reset, take the main containment lift to level 6 and find the Tier 3 door for Mycofields. Do not confuse it with the nearby Tier 5 mirror-world door.
Before entering, trade one Air Compressor to the Blacksmith for a Fire Proximity Suit, or assemble suitable heat resistance. Bring drinking supplies and a Lab Mask or other Airtight Seal protection against spores. Heat protection does not make jumping into lava safe.
If you lack the trade item, make an Air Compressor at a Crafting Bench from 1 Canister + 1 Pressure Gauge + 1 Reinforced Hose + 1 Chain. The Manufacturing supply run explains the reinforced hose, which is not a plain Hose.
Inside, search the traversable rock paths for Anteverse Gel pickups while working upward with the natural jump pads. Keep at least ten Gel for one Antethermite charge. The world has no unlocked completion shortcut; its exit is at the top. Plan enough supplies to reach it instead of assuming the entrance will become a convenient return gate.
This is also the region for Mushroom Peccaries and Carbuncle Mushrooms. If Gel is your progression blocker, secure it before spending the trip on optional creature farming.
Finding the relevant recipe
Read the “Webbing infestation” or “Hot Stuff” email attachment, or collect the Antethermite components. At a Crafting Bench, one charge uses:
| Ingredient | Amount | Preparation |
|---|---|---|
| Anteverse Gel | 10 | Bring back from Mycofields |
| Soil Bag | 1 | Reserve from your building/farming stock |
| Metal Scrap | 1 | Reserve from dismantling supplies |
| Lab Burner | 2 | Craft the components before the expedition |
Use the finished charge at the Vacuum Chamber’s webbing in the Lens Epicenter. Antethermite also clears the Laser Lab obstruction in Adjustment; it is not a replacement for every keypad.
What if you have Antethermite but remain stuck?
| Symptom | Check before spending more materials |
|---|---|
| Keypad refuses access | Hacker tier and the door’s clearance |
| X-ray wall remains active | All four Essence modules, not Antethermite |
| Cannot craft Antethermite | Discovery attachment, research, bench and all four ingredients |
| Wrong goo-covered door | Confirm Vacuum Chamber or the Laser Lab obstruction |
| No Mycofields objective | Finish the security reset; merely exiting the store is not that reset |
After opening the Vacuum Chamber, continue through the newly available Security route. Early progression distinguishes this checkpoint from completing the whole game.
