Dark Sector/Nightmare Fuel


 * Dark Sector scared the crap out of me. The first two levels of the game made it out to be a third person shooter with some interesting weaponry. Cue much shouting of "fuck! fuck! shit! arrrgh!" when you first meet the Infected. In a sewer. Where the lights go out. And you are in complete darkness. And all you see is faces and hands reaching out to you with each muzzle flash from your pistol. And the horrifying click when you run out of ammo.
 * More subtly disturbing is the quality of the voice acting for the Lasrian troopers. If they see the Glaive coming towards them, their final words will be a desperate, pitiful scream along the lines of 'Someone help me!'
