X01 is live: Deep Vault keys, loot rooms and the race to extract
The Captain’s 301 key opens a Vault gate and a loot room. A deeper core objective and closing exits give you separate reasons to stay—or leave.
Use X01 → Free Roam if it appears in your deployment menu; fresh-account eligibility is unknown. Deep Vault 301 is reported to stay in your inventory at the main Vault gate and be consumed at its numbered room. Supply Depot and Data Center offer different Encoder branches; Engineering produces Small Test Chamber. Ingredients are documented for nine X01 Printer recipes. Exact armor protection, guaranteed loot and task-specific death or squad credit remain unknown.
- 301 card: retained at the main gate, consumed at its numbered room
- Supply Depot: Maintenance / Executive; Data Center: Engineering / Audit
- Engineering Access produces Small Test Chamber
- Staff emergency card is consumed when its shaft unlocks
- Nine X01 Printer recipes have documented ingredients; FOB costs remain separate
- Updated November 7; exact armor protection, guaranteed loot and some completion rules remain unknown
Launch report, updated 7 November: Plan around X01’s separate Vault cards, Encoder branches and Printer recipes. Choose a practical goal before deploying: an Order, a numbered loot room or the deeper Vault core.
The X01 access guide covers direct deployment and the physical Hajin entrance. If X01 → Free Roam appears in your deployment menu, you can enter directly; fresh-account eligibility remains unknown. Use the Orders walkthrough for task-specific completion conditions.
A Vault gate, a numbered room and the core are different goals
The Captain is a reported source of Deep Vault 301. The card is reported to be retained when opening the main gate at C2, then consumed by its matching numbered room. A Captain drop is not guaranteed.
The core has another sequence: an upper terminal starts opening/defense, while the computer on the central glass case offers Neutralize Bioweapon. Opening a loot room or the core alone does not replace that final interaction. Follow the Vault guide for the supported sequence.
Encoders have different menus
| Station | Menu choices |
|---|---|
| Supply Depot | Maintenance Access; Executive Access |
| Data Center | Engineering Access; Audit Officer Access |
Choose Engineering Access to encode a Small Test Chamber card for the Tech Lab at F4. An Executive-room route to 406, separate from 301, has also been reported; that pickup is not guaranteed. A separate Ultra X01 Vault DRC Locker Key is intended for the DRC weapons locker inside the Deep Vault, but its acquisition and contents remain unknown.
Pick the exit before another detour
The Staff Emergency Exfil Keycard is consumed when unlocking an emergency shaft. A separate Wheelson Remote Module leads through local-console and Power Generators controls; it is not Prototype K9 Core V2. The boarding/departure countdown is reported as 25 seconds, even after the whole squad boards. Allow additional time for the lift to arrive. Use the exfil guide for the distinct routes.
Prepare ingredients for the X01 Printer
Ingredients are documented for nine X01 Printer recipes. The 3.5-Plate Armor Vest requires 1 Specter Fabric Sample + 2 Power Regulators + 5 Structural Alloy. The Staff Emergency Exfil Keycard requires 2 CPU + 4 Printed Circuit Boards + 8 Control Units. Argonaut Armor is a separate Fire Support item, not another name for that vest.
Use the crafting guide for all nine X01 recipes. Check the FOB menu for its own costs and unlocks; exact DMZ armor protection remains unknown. K9 V2’s purpose, death/reset and squad-credit rules, guaranteed loot and the full underwater reward chain remain unknown.
Quick questions
What does the Deep Vault 301 key open?
It is reported to open the main Deep Vault gate at C2 without being consumed there, then be consumed at its matching numbered room. The Captain is a reported source; a drop is not guaranteed.
Do you have to kill The Captain to enter the Vault?
The Captain is a reported key source, and an Executive-room route to 406 has also been reported. Killing The Captain is not a confirmed requirement for every Vault visit.
How does the Encoder route work?
Supply Depot offers Maintenance and Executive Access. Data Center offers Engineering and Audit Officer Access; the Engineering output is Small Test Chamber. These are station-specific branches, not one identical menu everywhere.
What does emergency extraction require?
The Staff Emergency Exfil Keycard unlocks a shaft and is consumed on unlocking. A separate Wheelson Remote Module and Power Generators route uses different controls. Follow the dedicated exfil guide for the route you choose.
Can you craft 3.5-plate armor in X01?
The X01 recipe for the 3.5-Plate Armor Vest requires 1 Specter Fabric Sample, 2 Power Regulators and 5 Structural Alloy. Argonaut Armor is a separate Fire Support recipe. Exact DMZ protection values remain unknown.
