Hack
Hack governs success in hacking keypads and secure crates. GameBanshee says technical skills reduce task difficulty by 10% each but do not reduce ICE Nodes; software governs technical skill levels, with a maximum level of 3 per software category.
How it works
Hack can open access to passcode-gated areas, locked containers, and security systems. The other guide says hacking security stations can disable cameras and turrets, and level 3 or higher can let the character control a turret after disabling it. Technical tasks can have minimum skill requirements.
