...but even on normal it has the kind of coked-up, hyper-active super guards that can hear a footfall on marble two storeys down on the street below, and will go instantly from normal patrol mode to AYYYAYAYAYAAAAAGH! waving their sword at a dead run at you when they've spotted you at four o'clock from fifty feet away. Irritating and immersion-breaking, to put it mildly. That being said, the rest of the experience is so high-quality it makes the omniscient guards tolerable. Just.

That's the thing with making the missions much harder than the original missions were.
