Not a steam achievement, but…
My dad was playing Munch’s Oddysee many years ago. In that game, you get instructions at the start of each level from a spirit standing inside two rings of rocks on the ground. If you need instructions again, the game tells you to stand in the outer ring and push the action button. My dad, who isn’t the most skilled controller handler, got the game to say something i had never heard.
He stood in the inner ring of rocks and pushed the action button. The game literally yelled at him, THE OUTER RING STUPID, STAND IN THE OUTER RING."
Good times.
Software Inc. Apparently people don’t like it when you take away their company car, vacation pay, end of year bonus, and end of year pay increase. Who knew.

Spiral Knights. What’s cool is I didn’t even realize I was in the running for this when I got it.

Something from a Cities Skylines DLC nobody played.
All of my 0.01ish% rarity cheevos are largely easy af things from DLCs or content updates of (somewhat) popular games that were released when most people had already moved on from these games
The really fucking hard stuff is usually around 0.5-3% (CoD BO3 zombies cheevos are insanely common for how hard they are)
Game: Crypt of the Necrodancer
Achievement name: Doppelgänger
Description: Kill a miniboss while possessing one of the same kind as Chaunter (SYNCHRONY DLC required)
You can find your rarest achievement by going to Steam, clicking your profile, edit profile, manage showcase, rarest achievements.
No achievement but today I’m poised to reach deep on night 5 in elden ring night reign. Apparently only 3% of players make it there.
Congrats on making it through evil nightreign
I have bunch of 2% achievements listed on my profile with the “Rarest Achievement Showcase”. I feel like they are not even worth mentioning here, compared to the 0.2% lists in this thread. Amazing achievements. I don’t know any other way to find the rarest (without involving any third party service).

0,1% Achievement of a very niche game
One of those dumb Forza Horizon missions where it’s not really difficult, just rare because you need to something very specific with a very specific car.
I have a bunch of those in Guild Wars 2, where a surprising amount of people ignore those quirky but easy little achievements, like dancing barefeet on a party airship or using a specific emote next to a specific NPC (both have around 1% unlock rate on a progress tracking fan site, so probably much less in the whole playerbase).
Yeah! Exactly! Mine was “Tortoise and Hare” where I had to join a race with an S class car with a D class car, or vice versa. No need to win it, just need to play.
It’s completed by 1.1% of players currently, but when I did it, it was only around 0.4%.
Is there an easy way to tell, I don’t pay attention to those usually
if you play on Steam and have at least a level 10 account, you can add a showcase to your profile that shows your rarest achis
Armello is a board game in which you move into enemy characters to attack them, and the character River can attack someone and deal one damage to them before starting combat.
Getting this required waiting to draw a teleport card, and be able to target it in range of a cluster of three enemies all at one health already (or retain enough damaging cards to bring them to one) before attacking all three.

I don’t really remember it, but it doesn’t look that difficult…


In Red Orchestra I have a melee kill with the binoculars:
A Sight For Sore Eyes Gain a melee kill with the binoculars
And in World of Tanks I have Kolobanovs medal.
I don’t remember what I did to get this, but apparently it involved eating corn. The game was Backseat Drivers.

The most rare ones I have are for delisted games like Marvel Heroes or Rocksmith. So here’s the next and more worthy two that were actually a challenge. Both are from Cave Story.
