This is an odd one. The AI feels a few decades too old. The wire puzzles were fine, but with only two types they got old fast. I fucking HATED the hacking minigame, the game would be a whole grade better without them. I also did not like running around the cramped station aimlessly with very few map markers, it made me want to drop the game quite a few times.
The gunplay felt a little weak at times, but I enjoyed the different combinations and ammo. I did enjoy the visuals a lot and the animations had character, the voice acting was also very enjoyable!
Also, despite being called one, the System Shock remake does not live up to the immersive sim reputation of being able to solve a puzzle in multiple ways.

TLDR; a great remaster in the sense that it keeps everything from the original game but does not hold up in terms of modern standards.
