Multitools are extremely handy inJupiter Hellas they allow you to use computer systems to unveil the entire map and show you where exits are, or even reveal tracking data that shows you where all enemies are.
Finding multitools is pretty much random unless you play as the Technician class who comes with three by default. You can find multitools in chests and by killing enemies. They appear as wrenches on the floor—just press A or Space to pick them up, and then when you find a system you can use them with, such as the JoviSec HelloSystem.

Upon interacting with a system like the JoviSec, a menu appears with options, and inside most options are the ability to use multitools to your advantage:
If you find a CoreTek Technical Machine on your run, you have the option to use some of the charges of the machine and turn them into more multitools or use multitools to add more charges onto the CoreTek. It depends on how your run is going and what is needed at the time.
