Quite possibly the best fog simulation game every made.
Never before has the experience of moving about in dense fog been so perfectly captured. Your view is limited to about 15 feet in front of you. Simply breathtaking.
To make things even more entertaining, your character can fly. Finally, you can experience the sensation of complete directional disorientation and fog blindness at any altitude you choose. The sheer number of character and building models that you can't see if stunning. This is the most detailed, living cityscape that I've ever (not) seen in all my gaming career. The whole city probably bursts with little details and flourishes. You won't see any of it because of the fog, but I'm sure they must be there.
Hats off to to Titus Software. Now if they'd just get to work on that Deaf and Blind simulator, I'd be happy.
