If you haven't played System Shock 1 or 2, these are a must play FPS horror/action/stealth/hack/adventure game!
The original System Shock was made 1994 and was one of the most interactive sci-fi games made at the time. This is no run-n-gun arcade game! You can loot just about any container, solve puzzles, fight robots and zombified crew. The original game had clunky controls which made it very hard to play, but today it can play on just about any computer made.

There is an enhanced edition available on GOG which supports higher resolution and better controls

But Nightdive Studios is doing a complete remake of the original game with the Unreal Engine

Sadly Steam and GOG only offer the Windows version of the Demo
But there is a Linux demo out there somewhere... I was able to play it because I subscribed to their newsletter.

Relive the original horror game with beautiful graphics, physics... stunning animation and even-more-interactive objects.

The Linux demo ran fine in Mint with my GeForce GTX 1060. The audio was very echo-y but still worked. Their kickstarter has some tips about how to fix the audio...
