100%
Boasting 700 achievements, This forces you to beat multiple ****** campaigns with no HUD, no shield regeneration, and doubled enemy health, alongside grinding for multiplayer achievements that require incredibly specific circumstances
Halo: The Master Chief Collection
A community-invented milestone mentioned frequently on Reddit's video game communities. Players must beat multiple FromSoftware titles (such as Demon's Souls, Dark Souls 1–3, Bloodborne, Sekiro, and Elden Ring) consecutively without taking a single hit. Getting hit once means restarting the entire multi-game run.
The "God Run"
One of the toughest achievements, if not the toughest, in any Bethesda title, has to be Mein Leben from Wolfenstein 2: The New Colossus. You must finish the game on Mein Leben difficulty, which is the same as the second hardest mode, I Am Death Incarnate, except you can't die. If you do, you must restart the whole game again.
Mein Leben - Wolfenstein 2: The New Colossus
An anthropomorphic cup embarks on a journey and fights a series of bosses to repay a debt to the devil.
Cuphead
A highly demanding MOBA where climbing ranks requires deep macro knowledge, map awareness, and intense team coordination.
League Of Legends
This rhythm-based platformer has an achievement list widely described as unmatched in its insanity. It requires immense mechanical skill, thousands of demon-level attempts, and extensive grinds that can demand years of real-world time to fully complete
Geometry Dash
From the Five Nights at Freddy's creator, this mode forces you to manage 50 aggressive animatronics simultaneously, all set to their maximum difficulty rating of 20. It demands perfect mouse movement, precise audio cue recognition, and millisecond-accurate timing. Only a very slim fraction of the global player base has successfully beaten it.
50/20 Mode
For the purposes of maximum difficulty, this is the original version of the Infallible achievement in Fall Guys, which required you to win five matches in a row.
Infallible: Fall Guys
A brutally demanding, fast-paced precision platformer. It requires thousands of attempts, with its instant-respawn system helping players master the absolute pixel-perfect jumps required to progress.
Super Meat Boy
A tactical, punishing first-person shooter where map knowledge, precise gunplay, and communication are essential to avoid losing rank.
Rainbow Six Siege
Widely considered one of the most mechanically demanding action games to platinum. It requires masterful parry-or-die combat, multiple playthroughs to unlock all endings, and hours of grinding for skill trees and boss reflection
Sekiro: Shadows Die Twice
Celeste is universally acclaimed for its punishing platforming perfectionism. The ultimate challenge is the Golden Strawberry in Chapter 9 ("Farewell"). To earn it, you must complete a massive, multi-screen platforming gauntlet featuring hundreds of frame-perfect dashes without a single death.
Farewell Golden Strawberry
What's better than roaming around in pitch darkness without a flashlight while gruesome foes sniff out your fear? Doing so on Insane difficulty, for starters. This mean-spirited achievement involves completing Outlast 2 on the highest difficulty setting whilst bumping around haphazardly in the dark, something that only a tiny percent of the game's Steam players have managed.
Messiah: Outlast 2
Widely considered one of the most mechanically demanding games from FromSoftware, this game ditches dodge-rolling in favor of a fast, rhythm-based parry system.
Sekiro: Shadows Die Twice
Features a high skill ceiling where mastering movement—like aerials and dribbling—is mandatory to advance through the competitive tiers.
Rocket League
Achievements like "Solace" and the infamous White Palace task players with some ridiculously challenging platforming in a game that's arguably not built for it.
Hollow Knight
Community-made levels like Limbo feature a staggering array of fast-paced click obstacles, blinding visual memory puzzles, and speed changes that take top players tens of thousands of attempts over months of practice to complete.

Dark Souls 1
A Battle Royale Game
Apex Legends
Often regarded as the hardest game to 100%. It requires players to beat the game with every single character—including 'Coda', who dies if you miss a single beat or pick up any item—and complete runs with no items at all.
Crypt of the NecroDancer
This grueling PC Gamer-highlighted gauntlet forces you to fight 42 bosses back-to-back. Activating "All Bindings" strips away your armor upgrades, heavily reduces your health, restricts your damage, and limits your magic usage. A single slip-up at the 40-minute mark sends you back to square one.
The Pantheon of Hallownest (All Bindings) – Hollow Knight
One of the hardest achievements around is still Masterminds, which forces GTA Online players to complete three Criminal Mastermind scenarios with the same team of players on Hard difficulty without losing any lives on Setups or Finales.
Masterminds: Grand Theft Auto 5
