System Shock 2 · Technical skill
Cyber Affinity
Cyber Affinity, displayed as Cyber in the MFD, eliminates one filled node per skill level during a Tech Skill hacking sequence. The guide says its effect becomes more helpful later and for characters who hack often.
How it works
The source specifically warns that late-game hacking grids can be entirely filled with white nodes unless the character has some Cyber Affinity. This supports considering the skill for hacking-focused play, but the excerpt does not provide detailed thresholds or outcomes for each level.
