I haven't played many games in the "sneak around corridors while avoiding monsters you can't fight" genre, but I liked Phantaruk, it managed to spook me. Also I'm a fan of bleak sci-fi settings and this game has plenty of that going on.
Sadly, the game isn't devoid of technical issues, despite the low system requirements I still experienced stuttering at times.
Finally, what little voice acting there is is really good and I always enjoyed finding a new captain's log.
