What's the most Difficult game/mission you've accomplished?

[PriestTroit]

I beat Mile High Club on veteran difficulty in COD 4.

Bet you can't top that!

[xadu]

Dead Space impossible mode

I don't say Dark Souls, because I never finished it.

[Merlin]

I did a couple of Halo Reach levels on Mythic Difficulty.

[MadMummy76]

Got Gold, on every license test in every Gran Turismo game from 1 to 6.

[Last_Dragoon]

Getting Platinum on Final Fantasy X. Completing the sphere grid with all characters, beating all dark aeons and penance, and hardest of all...chocobo minigames.

[RetroRex]

Completed Killer Instinct on the hardest difficulty without using any continues.

[Omegapyrate]

Final boss of Silent bomber back in the glorious ol' PS1 days. That one really sticks out for me as a satisfyingly tough fight.

[Murray]

I managed to 1CC DoDonPachi once (got to second level of the second loop in one credit).

[Thomas_JCG]

"The Grey Mourner" in Hollow Knight. You have to take a flower from one side of the giant map to the other without getting hit or using fast travel, avoiding all manner of obstacles and enemies.

[Cosmocalypse]

Gears of War 4 Insane solo was pretty hard.

Flawless Raider on Destiny 1 back in VoG days was pretty hard as well.

Hard to narrow it down, but I think I have 3 decent ones.

I never really watched other people play smash bros, so I don't know how common this would be. When I used to play smash bros melee a lot more, one of the things I liked to do was play 3 on 1 team matches with 3 cpu players against me, and I liked practicing to see how high I could put the cpu difficulty and still be able to deal with the computers. Eventually I decided the high water mark I wanted to shoot for, was I wanted to fight 3 lvl 9 Ganondorfs with link and win. It took a while, and it was probably one of the hardest matches at least in smash that I've ever played. I won two or 3 matches like that and then won another with kid link but with the same ganondorf team.

The hardest path on starfox 64. Dunno what else to say about it other than that game was my frickin jam, and for a long time I had no idea how to get to the other planets. Eventually I found out from either rumors or something and clawed my way through the hard path and even got the true ending. Probably was one of the first times I had that experience of such formidable difficulty, but you overcome through painstaking trial and error, and finally got to the place I worked so hard to get to. Taking the hard path also gave more character backstory and stuff, and made the whole game feel way more rich and only fueled my hunger to find out what the real ending was.

Like Eldarion mentions earlier in the thread, Kerbal Space Program can be pretty hard and Kerbins two moons in the game can be challenging places to get to especially if you're relatively earlier on in the game experience. I wanted to make 2 rockets that were fit for landing on and returning home from the larger of the two moons in a similar style to the real apollo 11 mission, and I wanted to do it first with the lowest tier technology I could in the game, and then do it again with mid tier technology but try to mimic the apollo 11 lander and transit stage as closely as I could and both should be made as cheaply as possible. Wound up getting both rockets to work, although it wasn't without lots of challenges for their maiden flights. Most of the difficulty comes from the fact that the rockets were made with pretty much JUUUUUST enough fuel to make it all work. The thing is, in the Apollo mission, you had a command module that stayed in orbit and the lander that detaches to go to the surface. The lander however has to actually relaunch from the surface at a specific time and at a specific angle in order to perfectly meet back up with the command module and dock to get the guys home. Problem is, I have no idea how to plan that timing or angle, and if you launch into orbit badly, you can run out of fuel and not make it to orbit. So to redock to get back home on those first attempts flying those rockets were pretty nerve wracking. You're trying to do like 4 precise things all at once and you don't have that clear of an idea how it all works to maximize efficiency. But it worked out in the end.

[ From best to worst. I am not the best but I really enjoyed overcoming these games. ]

Left 4 Dead 1 & 2: Something to prove achievements before the nerfs on the zombies (before the nerf if the zombies landed a single hit = instant down).

XCOM EU: An Army of 4 achievement (use only 4 or less soldiers each mission) on Impossible difficulty. Got Lone wolf at the same time (clear a high mission with only ONE soldier).

Killing Floor 1: Hell on earth solo play.

Darksouls 1 & 2: Ending the game and even do runs (bow only run, crossbow only run, etc).

Arcade Game Ocean Hunter: Defeating Rahab (I would KILL for a sequel or even a remaster of this game).

Arcade Game House of the Dead: Defeating The Magician.

Arcade Game Carnevil: Defeating Ludwig von Tökkentäkker.

Good to hear that Saskia, and yeah the Difficulty spiked hard, but at least it was near the end and difficulty didn't spike all over the place like some other games I like.
X-Wing Alliance I'M looking at you, damn that first Rebel Training mission and the Gamma Class Assault Shuttles!
Fast enough you couldn't get rid of them, and thanks to their turrets you couldn't kill them with Proton Torps, god those assault transports and assault shuttles were nightmare fuel.
Honestly I'd rather take on a Star Destroyer than those.

[Juan-ton_Soup]

Little brother and I took turns trying to beat that game on the GamCube recently. That fight is hard on those GC controllers! And as a little kid, however, that was a huge accomplishment just figuring that out haha

[xadu]

I finished Alien isolation on nightmare difficulty, without saving, without lockers, without dying, without using the flamethrower, and trolling the alien by making noises, attracting it to explosive traps, making him to kill all the humans, and killing all the androids.

I never felt so much anxiety of suddenly being killed. I suffered all of it.

I uploaded it to youtube, but then google decided, without my permission, to force me into google+, and unified my work e-mail account with my unrelated gaming channel.
I had to close my youtube account to stop my bosses from having youtube showing them my gaming life, mixed with my work life. Until that point, I considered my gaming life a private, different identity on Internet.

I had put a lot of love on my gaming channel, and I was sad to be forced to close it because of Google's absolute lack of respect for my privacy.

I stopped trusting google, and also closed my gmail account. I will never trust google again.
