That One Boss/Stealth Based Game

Examples of in s include:


 * Say Hello To My Little Friend from Hitman 1 is the hardest mission in the game, and the only target in the series to be inexplicably durable. First off, it's actually impossible to stealth through, as at some point, you will make yourself known. Then there's the objective to blow up the drug stash, which is protected by guards who will shoot on sight. Then you have to do a shootout against a coked-up Tony-Montana wannabe with a full-auto machine gun, who only goes down after filling him with his weight in lead. Then you have to make a mad dash to the plane while under fire. Oh, and this game doesn't have any way to save mid-mission, so you'll have to do everything all over again if you fail. Have fun.
 * This level becomes ridiculously easy, however, if you found the sniper rifle in the previous level. You can see him and snipe him through a window, and save yourself all that trouble.
 * This is an odd case. It takes less than ten shots with a pistol to kill Tony Montana. You just have to wait a while between shots. He has a period of Mercy Invincibility after each successful hit. If he doesn't say anything when you shoot him, you haven't waited long enough. It makes the fight easy but boring. The rest is crazily hard, though. It's best to kill Montana first after you've knifed everyone in the house in the right order, then go to the drug stash.
 * The End is enough of a That One Boss that Konami put in two different ways to defeat him without fighting. If you don't kill him at the dam or wait for him to die of old age during the boss fight, you're in for one of the tough sniper duels in gaming. Prepare to spend a good hour fighting him. Finding where he's hiding without being spotted yourself is damn hard, as he's got fantastic camouflage. Picking a single spot and waiting in first-person mode to ambush him results in him knocking you out from behind. Letting him see the glint off your scope gets you a tranquilizer round in the eyeball. And don't expect him to sit still either; he's stalking you even while you're looking for him. And if you want to get the stamina-kill, you have to do this all with your tranq-pistol.
 * Let's not forget that he could shoot you while you weren't even playing the game. And he's even worse on boss survival (hard mode): He knocks you out with a single shot (to be fair, you also kill him with a single headshot), his position on the map is randomized and since you obviously want to beat the highscore if you even bother fighting him, you have to be fast about it. Oh, and as soon as you have a straight aim at his you have like 0.5 seconds to fire before he notices you and runs away.
 * Here's another handy tip for finding him, if 90% of the trouble you've been having is running around Sokrovenno South for hours just trying to find the bastard - did you know that The End fight actually consists of three different areas? That's right, those cliffs he's shooting from between long stretches of seemingly vanishing completely are actually accessible by you, the player, and all this trouble you've been having is your own damn fault for not realizing he can run through the loading screens into different areas unlike every single other boss in video game history. Completely frustrating, especially if the person you ask to kill (tranq) him for you only chooses to divulge this useful tidbit well after you've handed over the controller...
 * The Fury is a likely candidate. Early on in the fight, it's as simple as swerving between corridors and taking potshots at him. Soon enough, he gets pissed and starts going all-out with his flamethrower. Suddenly, he now always knows your exact position, and starts shooting his flamethrower down entire corridors. Not only does this give you a small margin in which to actually nail him with your weapons, but the fire also makes it a bit hard to even see where you're aiming.
 * It's the Hind-D fight in Metal Gear Solid. You may not know you can destroy the gun-cams with stingers and end up losing rations running up the damn stairs - making what should be an annoying boss almost impossible, not to mention it's really hard to get good 360 cover while still having a good area to aim the missiles.
 * Psycho Mantis, who is fairly easy - once you've figured out the fourth-wall-raping puzzle you need to solve just so you can hit him at all, of course. He can still be a pain though with him throwing all of that goddamn furniture everywhere.
 * Sniper Wolf can be this on the first playthrough since you are unlikely to know where Diazepam is and without it, the PSG-1 is a pain to control.
 * That being said, the second time Snake faces Sniper Wolf is preposterously easy, as she can be taken down with Nikita rockets while Snake is safely out of range.
 * Metal Gear Solid Peace Walker had the AI weapons, since they take so long to take down and some of their attacks can be real tough to dodge. However, the second battle with Peace Walker itself is probably the worst, since it will also sometimes start a nuclear launch sequence, in which you have one minute to damage it enough to stop it, or you get game over and have to restart the entire fight again. It also has EMP pulses which will stop rockets from hitting it.
