Farflame spotted this article about the new System Shock on PCGamesN - some things will change:

System Shock remaster will have "modern level design principles" and other changes

Developers Nightdive Studios want the System Shock remake to be as faithful as possible, but they're not planning on ignoring the past two decades of progress in the craft of making videogames. 

The team has been talking to some of the original Looking Glass Studios developers, and one of the biggest takeaways was that, if they made the game now, there are a bunch of things they would do differently.

 

"Whenever we look at the design, or art, or audio even, we ask ourselves “What would LGS do?” say Nightdive in a Kickstarter update. "The answer becomes clear after understanding LGS was about innovation, trying new things and bringing together concepts unheard of in games before them. We see ourselves as maintaining that tradition, and chat with the LGS guys to ensure what we’re doing holds up to their expectations."

Other than plugging plot holes and refining dialogue, the story will remain untouched. The original voice actress for Shodan is returning and they're letting her give input. Gameplay will also see a refresh, with combat given more depth and systems becoming more reactive. 

"Levels will harken back to the original game thematically, but the layout will see a pretty big change to apply modern level design principles for pacing and exploration," say Nightdive. "We’re not going to dumb things down, but we also don’t want to ignore the last 20 years of progress level design has made."
