This post will answer these questions and teach you how to use the Blackwall quickhack!

Clues about Blackwall in the Game
To have a more realistic and practical look at Cyberpunk 2077 Blackwall, we will need more information from the interactions with NPCs. Players will find out more and more details about Blackwall as they continue the story:
- “I Walk the Line“: Voodoo Boys are trying to reach beyond the Blackwall, and the NetWatch agents have caught the scent. Bryce Mosley reveals that people view the Blackwall as a great border wall and a one-time solution for humanity, but that is incorrect. The Blackwall is more like “a torn open trash bag taped over a busted window.”
- “Transmission“: Brigitte tells V that the Voodoo Boys are trying to breach the Blackwall and contact Alt because they believe that the collapse of the Blackwall is inevitable. Preparing ahead and striking a deal with Alt can give the gang an edge in the post-Blackwall era.
- “The Damned“: Slider, the netrunner for VDBs, says that Songbird is using the Blackwall protocol to contact V’s Relic and she is a walking bomb to the collapse of Blackwall and humanity. Later, the DLC reveals that Songbird is deeply infected by the Blackwall and seeks the same cure as V from Cynosure.
In conclusion, Cyberpunk 2077 Blackwall is the last defense to hold off rogue AIs from the net space of human beings, yet many characters in the game are challenging or taking advantage of this defense for political leverage and gains, including President Myers of NUSA, who ordered Songbird to tap into the Blackwall.

How to Gain Access to the Cynosure Facility?
For players who want to forge the Blackwall Quickhack, they have to get into the facility by going through the main job.
The only way to do so is to betray Songbird at “Firestarter”. When V and Songbird are in front of the neural matrix machine at Hansen’s place, players need to choose:

Later on, at the mission “Somewhat Damaged”, V will enter the Cynosure Facility to rescue Songbird after hijacking the MaxTech transportation team.

Where Is the Cyberpunk 2077 Blackwall Quickhack?
Cyberpunk 2077 Blackwall Quickhack is located at the Experimental Prototyping Room in the abandoned Cynosure Facility. It was a tech developed by Militech. The facility was for developing the counter-Relic technology, the Neural Matrix.
The room lies next to the Observation Room and Data Analysis & Research, and it is on the way to the Core Control Room. Therefore, it’d be best to finish disconnecting all the servers first, following the main job. And then get into the Prototyping Room on your way to the Core Control.
Players need level 15 Intelligence and above to crack the code of the door. The code is 714212. Typing in the code if you do not have level 15 intelligence.
Players can find a suitcase on the showcase of the Experimental Prototyping Room at the Cynosure Facility. Inside the suitcase is the Militech Canto Mk.6 Cyberware blueprint.
However, to build this cyberware, players also need the behavioral system component from Cerberus (the deadly robot roaming in the facility). So don’t forget to collect the component from the robot after exiting Songbird’s cyberspace of her Brooklin apartment.

How to Activate Blackwall Quickhack?
Players can check the Crafting menu and find the Militech Canto Mk.6 showing on the list. But to craft it, players need to wait for a secret call to unlock the mission “This Corrosion“.
To trigger this message, players can skip time for 24 hours after finishing the ending of the Phantom Liberty DLC. The message will lead players to a cyberware shop called Edgenet at Kabuki. Yoko, the front desk girl, will help players decode the behavioral system component.
After that, players can craft the Militech Canto Mk.6 at the crafting menu, with
- 12 Tier 5 Quickhack Components
- 50 Tier 5 Item Components
- Cerberus’ decoded behavioral system component
Blackwall Quickhack in Cyberpunk 2077 is not an independent quickhack. It is engraved into the Militech Canto Mk.6 Cyberware. In short, to use the quickhack, players must equip the Militech Canto Mk.6 Cyberware on their Operating System. The Blackwall Quickhack will be available once V equips the Militech Canto Mk.6 through a cyberdoc.

What Is the Effect of Blackwall Gateway Quickhack?
Effects and Shortcomings
Cyberpunk 2077 Blackwall Quickhack can cause lethal damage to enemies and can spread to up to 5 enemies as long as they are within 20 meters. Each spread will have a shorter uploading time but cost more RAM than the last spread. Players can also reduce half of the RAM cost by deducting HP instead.
Using Blackwall Quickhack as a standalone hack is not really worthwhile. Although the damage is lethal, the quickhack takes a long time to upload, and it is hard to spread to other enemies if they do not stand next to each other. It is a waste to deal with normal enemies with the Blackwall Quickhack because there are so many other, more efficient ways to take them down faster and easier. However, if it is to deal with robots or bosses with high HP, Blackwall Quickhack is a convenient way to deal a large amount of damage.

Possible Solutions
To solve the shortcomings of Blackwall Quickhack, there are several intelligence perks that can come in handy.
- Hack Queue: This perk increases the speed of the second uploaded quickhack by 30%. Players can unlock this perk and equip a low RAM cost quickhack on the Militech Canto Mk.6. Use the low RAM cost quickhack first, and then add on Blackwall Quickhack to increase the uploading speed.
- Overclock: Replace the insufficient RAM with a Health cost. Each extra RAM unit costs 10 Health instead. This can reduce the RAM cost during the spreading of Blackwall by half, and compensate for the low RAM situation.
All in all, to make Blackwall Quickhack efficient, players need to combine it with the intelligence perks to increase its upload speed and reduce its RAM cost. At the same time, because of the Health deduction, players need to add on perks that can recover HP and equip cyberwares that can increase HP level in general.

FAQs
Can you use Blackwall in Cyberpunk?
Yes. Blackwall Gateway Quickhack is a combat quickhack in the Militech Canto Mk.6 Cyberware. Players can deal lethal damage to up to 5 enemies within 20 meters by uploading the Blackwall Quickhack to the enemies. The use of the Blackwall Quickhack will come with voices from Blackwall. The graphics of enemies being consumed by the Blackwall are also very similar to what Songbird does when she unleashes the Blackwall’s damage in “Firestarter”.
What happens to V beyond the Blackwall?
In the mission called “Transmission“, V goes beyond the Blackwall for the first time to find Alt Cunningham. V communicates with Alt and talks about the plan of having her help extricate the Relic once V has access to Mikoshi. Johnny Silverhand also appears in cyberspace beyond the Blackwall and tries to talk to Alt. However, the AI is no longer the original Alt. Only a small part of Alt’s image and consciousness is preserved.
If players choose to help the NetWatch agent, Alt will cleanse all the VDBs’ netrunners who try to breach the Blackwall with V.
What does the Blackwall Gateway do?
Blackwall Gateway is a combat quickhack embedded on the Militech Canto Mk.6 cyberware. The Cyberpunk 2077 Blackwall Quickhack can spread to up to five foes within 20 meters and deal deadly damage to them. Although each spread will take less time to upload, it will use more RAM than the previous one. By subtracting HP instead of RAM, players can also cut the cost of RAM in half.
Conclusion
Cyberpunk 2077 Blackwall is a firewall in cyberspace that can protect human beings from being infected by rogue AIs. However, in the game, the so-called last hope of humanity appears to be a valuable resource served on a silver platter. VDBs try to collaborate with Alt beyond the Blackwall to gain an advantage for the future. President Myers has Songbird tap into the Blackwall for political leverage. V, in the ending of betraying Songbird, can make use of the Blackwall as well. It is more than accurate to describe the Blackwall as “a torn open trash bag taped over a busted window.”
As to the Blackwall Gateway Quickhack, players can only obtain it at the ending of betraying Songbird. The process of getting it is by no means easy. The roaming Cerberus in the rooms and the settings in which players can not fight back simply turn Cyberpunk 2077 into a horror game. Adding on the fact that the Blackwall Quickhack will take some thinking and strategies to function efficiently, players can consider if this tech worths betraying Songbird and going through the nightmare Cynosure Facility.
