In Grey Hack, terminal has a fundamental role, it is also based on actual unix commands and will be an indispensable tool to perform successfully hacking actions.
When you increase your reputation on the network you can choose to join a group of hackers to carry out coordinated attacks or even create your own. Although if you prefer you can choose to go solo.
Keep in mind that a hacker does not have to act economically, so you decide which missions you accept and if you agree with its consequences.
Social engineering is a powerful tool and, in the most difficult cases, can be very helpful. This means that you can try to trick the user of that computer into giving you their credentials, confidential information about another person, etc.
Going to improve your work station will also be important for more and more professional jobs.
