1 Mr. Perfect (Mega Man 10)
"Mr. Perfect" from Mega Man 10 is an achievement that truly tests your gaming prowess and patience. It requires players to complete the entire game without getting hit even once. One mistake and you're starting over! According to Xbox360achievements.org, nobody has EVER gotten this achievement. You have to complete the whole game without taking damage. And the worst part is, it's only 30 Gamerscore.
I tried beating it before and started over 27 times before I quit.
2 If They Came to Hear Me Beg (Halo: Reach)
"If They Came to Hear Me Beg" from Halo: Reach is an exercise in precision and timing. To earn this achievement, players must perform an assassination on an Elite to survive a fall that would've been fatal. Easier said than done! A tip: play Pillar of Autumn co-op legendary. I couldn't believe I got it when my friend and I were playing.
3 Mile High Club (Call of Duty 4: Modern Warfare)
"Mile High Club" from Call of Duty 4: Modern Warfare is an achievement that is notoriously challenging. It requires players to complete the epilogue mission on Veteran difficulty in less than 60 seconds. Only the quickest and most tactical players will unlock this one! I have done this on 4 different profiles and it still finds a way to weasel out my inner rage. By far the hardest achievement.
The most difficult task I have ever accomplished in any game.
The hardest achievement of the whole game.
4 Time Travel Will Tell (Call of Duty: Black Ops)
"Time Travel Will Tell" from Call of Duty: Black Ops is an Easter Egg achievement that involves a lengthy sequence of steps during the Zombie map, 'Shangri-La'. It requires thorough knowledge of the map and perfect execution. This is the hardest achievement I have tried to get in my entire life. I tried to do it with other players, but it was an epic failure for me, of course. The hardest I ever did. Do you know what I'm saying?
Yes, dude. I understand your pain. It took me 4 hours to get it in one game. My first attempt was joining a random lobby, and we ended up completing it. Hardest Easter egg besides Buried's.
Requiring 4 skilled players, a wonder weapon, and tons of tasks that need to be completed.
5 I'm A Golden God! (Super Meat Boy)
"I'm A Golden God!" from Super Meat Boy is for the truly dedicated. To unlock this achievement, you need to 100% the game, which means completing every level without dying, finding all bandages, and conquering all warp zones. It's a real test of patience and skill. Just completing the game was hard enough. Now they want us to 100% it? That means we have to go through the entire dark world, collect all of the bandages, and complete the bonus challenges. Not happening.
The hardest part of this challenge is you could look up EVERYTHING and still not be able to get it. This achievement popping was the most satisfying accomplishment of my 360 career.
6 World Champion (Ghost Recon: Advanced Warfighter)
"World Champion" from Ghost Recon: Advanced Warfighter challenges your multiplayer prowess. The achievement requires ranking 1st on the game's global leaderboard - no easy feat, given the highly competitive player base. You have to be the #1 best player in multiplayer. Ever. Of all time.
7 Seriously 2.0 (Gears of Wars 2)
"Seriously 2.0" from Gears of War 2 is a grueling grind. To unlock this achievement, you have to kill 100,000 enemies, a feat that requires considerable time and determination.
8 A Monument to All Your Sins (Halo: Reach)
"A Monument to All Your Sins" from Halo: Reach is the ultimate test for any Halo fan. You'll have to complete every mission in the game on the Legendary difficulty, solo. Prepare for a tough fight!
9 Way of the Master Ninja (Ninja Gaiden 2)
"Way of the Master Ninja" in Ninja Gaiden 2 is reserved for the most skilled players. To earn this achievement, you have to complete the entire game on the hardest difficulty, Master Ninja. I don't vote for achievements that I don't have, so this is the hardest achievement I achieved. It brings 100 Gamerscore. And yes, there are harder ones on this list, like "My Kung Fu Is Stronger." They require a long time. They are not "hard."
10 Ensemble Cast (Call of Duty: Black Ops)
"Ensemble Cast" from Call of Duty: Black Ops involves a complex series of tasks on the 'Call of the Dead' Zombies map. This achievement requires tight coordination and cooperation from a full team of players to unlock.
The Contenders
11 Seriously (Gears of War)
"Seriously" from Gears of War is aptly named, as it requires serious dedication from the player. To unlock this achievement, one must kill 10,000 players in versus competitive matches. It's a marathon, not a sprint!
12 Something To Prove (Left 4 Dead)
"Something To Prove" from Left 4 Dead is one for the team players. It requires you to survive all campaigns on Expert difficulty, which is no small feat, as the zombies are much tougher and your AI companions are not. You'll definitely need a good team to make it through this one!
13 7 Day Survivor (Dead Rising)
"7 Day Survivor" from Dead Rising is one of the most grueling video game achievements around. To get this, you need to survive for 7 in-game days in Infinity Mode, which equates to about 14 hours of real-time play without being able to save. Be sure to clear your schedule for this one!
14 Insanity (Mass Effect 3)
"Insanity" in Mass Effect 3 requires players to beat the game on the hardest difficulty setting. You'll need to master combat tactics, power usage, and squad management to take down the tougher enemies this mode throws at you. Start with level 60, max everything, and then cover behind walls until the end of Earth.
15 When Pigs Fly (Minecraft)
"When Pigs Fly" from Minecraft takes patience and a bit of luck. This cheeky achievement involves riding a pig off a cliff and having the pig take damage from the fall. It's a quirky, fun challenge in line with Minecraft's creative spirit.
16 Lost Little Girl (Call of Duty Black Ops 2)
"Lost Little Girl" from Call of Duty Black Ops 2 requires not only skill but also in-depth knowledge of the game. This achievement involves completing a complex easter egg on the Origins map in Zombie mode. A team with good coordination and understanding of the game mechanics is essential for this one. What about this one? I bet 90% of you haven't finished it. (It's to finish Origins and find Samantha.)
17 Vidmaster Challenge: Annual (Halo 3)
"Vidmaster Challenge: Annual" from Halo 3 is a unique achievement. To unlock it, you must complete the final mission of the game on Legendary difficulty with 4 players, and everyone must ride the final Warthog run in Ghosts. It's a true test of teamwork and Halo skill.
18 The End (Minecraft)
"The End" from Minecraft requires the player to defeat the Ender Dragon, the final boss of the game. This achievement takes time, preparation, and a lot of courage to face one of the toughest creatures in the game.
19 My Kung Fu Is Stronger (Mortal Kombat)
"My Kung Fu Is Stronger" in Mortal Kombat demands dedication to a single character. To unlock this achievement, you must master a single character, which includes winning 100 matches, landing 100 fatalities, and more. Prepare to get to know your chosen character really well! Gain mastery of all 28 fighters. Gaining mastery of a character also requires you to play as them for 24 hours of gameplay, meaning 28 total days of gameplay (even idling, until your Xbox stops working) just to get an achievement. Ridiculous.
20 Saint (Dead Rising)
"Saint" from Dead Rising challenges players to save a whopping 50 survivors throughout the game's campaign. This requires meticulous planning and efficient time management to successfully pull off. To get this achievement, you have to rescue almost every survivor in the game. It's no cakewalk, especially with the AI.
21 Have Car, Will Travel (Midnight Club: Los Angeles)
"Have Car, Will Travel" from Midnight Club: Los Angeles requires you to drive a total of 5,000 miles, equivalent to driving across the continental United States from coast to coast. It's not a quick achievement by any means, but you'll have plenty of time to enjoy the sights and sounds of virtual Los Angeles. This isn't the absolute hardest of achievements, but it's still really hard and time-consuming.
22 Seriously 3.0 (Gears Of War 3)
"Seriously 3.0" from Gears Of War 3 is a daunting task and one of the most time-consuming achievements in the game. To earn it, you need to reach level 100 and earn every Onyx medal, which includes everything from killing enemies to reviving teammates. It's a testament to your dedication to the game. To get this achievement, you have to earn all 65 ONYX medals and be at least level 100. According to the Xbox One (yes, Gears of War 3 is backwards compatible), only 0.45% of players have earned the achievement. It might be impossible today since one of the medals is for tournament participation (Bronze is 5, Silver is 10, Gold is 20, and Onyx is 30), and I don't think they still have Gears of War 3 tournaments anymore.
23 The Bladder of Steel Award (Rock Band 2)
"The Bladder of Steel Award" from Rock Band 2 truly tests your stamina (and your bladder). You need to complete the Endless Setlist 2 without pausing or failing. That's 84 songs in a row, requiring about 6-7 hours of continuous play. Better hold off on the drinks for this one!
24 Fashion Show (Monster Madness: Battle for Suburbia)
"Fashion Show" from Monster Madness: Battle for Suburbia requires you to acquire all costumes. This involves hunting down and collecting various outfit pieces throughout the game, offering an incentive to explore every corner of the game’s environments. You have to beat every level on Madness without dying.
25 The Dark Soul (Dark Souls 1)
"The Dark Soul" from Dark Souls 1 is the ultimate achievement for those who wish to fully master this infamously difficult game. To earn it, you need to collect all other achievements, effectively requiring you to complete nearly every single challenge the game has to offer. Get ready for a real test of your gaming prowess.
