Nightmare Fuel: Shadow Man
The Playrooms no doubt freaked out anyone and everyone who played the game as it combined innocent infant bedrooms with blood-stained killing rooms while the laughing and crying of babies mixed in with the combo soundtrack of a music box and the sounds of some kind of power tool cutting into something wet and crunchy. The Playrooms area was pure psychosis in video game form.
The lairs of the Five weren't much better, including a derelict, abandoned New York apartment building full of corpses and an attic full of enough blood to form literal pools and waterfalls.
The underground London subways in which Jack The Ripper lives.
The music that plays in Jack's shrine (it's a heavily distorted version of "Moonlight Sonata"'s first movement, with the notes, not the song, backmasked) is probably the most disturbing tune in the game, and considering how pants-wetting most of Tim Heywood's soundtrack is, that's quite a mouthful.
The Texas prison where all the guards and most inmates have been killed and reanimated as headless zombies where a disco-obsessed nutball, a Vietnam war veteran and an insane doctor reside.
Even the more mundane areas usually have some creepy factor to them.
The final villain just happens to be the very same "Legion" that Jesus encountered in the Bible. He's a lot scarier here than he was back then.
The sequel, however, seemed less so, as it felt more akin to typical video game dungeons. But, the main hero was now an emaciated skeleton ghoul rather than a muscle man with a mask in his chest.
There's an enemy type in Deadside that starts popping up when you enter the Asylum, all based on hulking figures in masks, who make this horrific distorted pig squealing noise when they attack you.
The Asylum level called "Playrooms" sounds like fun, doesn't it? Interestingly enough, many areas in Liveside are even scarier. It comes to a head in the dilapidated New York tenements, which features very few enemies but is drenched in terrifying, pitch-black atmosphere. The music does not help at all.
It gets even worse: the desiccated corpses in the tenement all have tape recorders playing a two-second loop of someone whimpering in most versions, but the PC edition has them play a longer clip consisting of the Home Improvement Killer forcing his hysterical victims to repeat Mark 5:9 as they sob and plead for mercy. Yeesh.
To one up the above comment, picture this scenario: You're in Deadside and you see a waterfall of blood. Normal given the circumstances of where you are. Now, back in that liveside domain you see another waterfall of blood like in Deadside and you start thinking to yourself: "Ya know what? I think Avery's killed a little more than twelve people..."
Gardelle County Jail is littered with the headless corpses of Dr. Batrachian's victims. Even Mike is freaked out when they start getting up and attacking him ("This isn't happening!"). The harsh, ragged breathing noises these victims make through their exposed throats is deeply unnerving.
Jack the Ripper's domain is also quite creepy, especially when you come upon his private chambers and find his "homework" hanging from the rafters. The fact that the bodies are concealed under bloody sheets mitigates it only slightly.
When you first encounter Marco, he starts making a disturbingly cheerful rant about the upcoming apocalypse that really gets creepy when he starts talking about Michael's dead brother, Luke. It's the tone that really sets it off...
Marco: And he's screaming for his mommy but his mommy's gone down Deadside way! She can't help him and neither can you!
