A classic genre defining game which in its time went under appreciated. but to this day remains a masterpiece.
Taking queues from Ultima Underworld (same developer) your character starts with nothing and very little information to go on - but the overall feeling of being overwhelmed at the task before you.
You find yourself crawling through a creepy space station littered with dead people; the only human interaction being data discs and email files to advance the story and your character. The hallways are haunted with the moans of the diseased and a little computer program named Shodan.
And she's quite a ****
If you can get your hands on this title - I recommend it, still to this day. It's been close to 10 years since I ripped open the plastic on that box, and I haven't yet forgotten.
