This is what I’m referring to.

Here’s one of the puzzles from the game.. Other puzzles had one or two nodes already lit up.

I’m not asking for solutions. I’m asking for what the logic of the puzzle is.

I did all the System Shock remake puzzles without guides or logic probes after looking up one guide for the wire puzzle because how the variables worked wasn’t intuitive, so I get what you’re saying. But like the wire puzzle, the node puzzles in SS2 aren’t obvious how they work.
