That One Level/Video Games/Stealth Based Game

Examples of in s include:


 * Hitman 2 has a level called Hidden Valley, where the sole objective is to get from one end of a valley to the other, evading swarms of ninja guards. This isn't actually all that hard in itself. However, the highly trained ninjas apparently do not have the slightest understanding of basic road safety and have a habit of getting themselves run over by the truck convoys going through the underground tunnel. This would invariably result in the body being discovered and the alarm being raised, ruining the player's chances of getting the top mission ranking of Silent Assassin through no fault of their own. This would happen about four times out of five and could happen at any point in the mission, even when you were just seconds from reaching the exit. The only solution was to just keep trying again and again and hoping you got lucky.
 * The Motorcade Interception mission of Hitman 2 is an exercise in hair-pulling because of the way the civilians are handled. Their starting positions and walking routes are randomized, and they run to get the nearest guard immediately if they see you with a weapon. This is mitigated somewhat by the fact that without a weapon, they don't even notice you exist. Unfortunately, this is a sniping mission, so you have to carry a rifle from either the start of the level or your contact elsewhere to the nest. AND you're liable to get noticed while you're waiting in the nest for the motorcade to pass by, AND it's quite possible to go through all of this and then miss the shot anyway. This is especially annoying if you're trying for Silent Assassin rating.
 * The very insanely, long stairway in the communications tower of Metal Gear Solid. You CAN'T avoid getting spotted by a security camera, even when the "Throw a chaff grenade before entering new doors" worked before, forcing Snake to run up an insanely long flight of stairs, being chased by a shitload of enemies—in a game where it's usually suicide to take on more then three or four enemies at a time. Oh yes, there's also the Guide Dang It that if you ran out of the room with the camera instead of rushing for the stairs, you're stuck in an infinitely respawning chamber with no way out (it's probably a glitch, but Unwinnable until you reload). Even after mowing all the enemies down, the towers are still irritating for the insanely long time it takes to go up and down it, even when Snake's running.
 * Stun Grenades every few floors. Takes much of the sting out of this level. Now, going all the way up to the roof only to find you skipped the rope by accident? That part's still a huge Guide Dang It.
