Games

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.

That one is from Witch It!, but it's bullshit, most of their achivements have those kind of extra conditions that make them hard to get (but also to prevent just cheesing them playing on an empty server so I guess that's fair)

This, from Tabletop Simulator.

probably this badge

as for strictly achievements, looks like it's from human fall flat. that game just spams you with achievements though.

This one I think =w=. I don't particularly care about achievements or getting rare ones, so I don't have any super extremely rare ones

My rarest achievement is for getting 32 silenced revolver kills in Red Orchestra 2 (0.3% of players). Technically its not too difficult, but since its a shooter with a fairly low TTK, you don't normally use the sidearm much. Further the silenced revolver is a pristige varient that has to be ground out using the original revolver, and performs worse than the unsilenced, so there is no reason to get the achievement except for completionism sake.

The achievement I'm much more proud of is Crypt of the Necromancer's Vow Down, for completing a full roguelike run with Monk. The gimmick with Monk is that the game is its normal roguelike-on-a-beat, but if you touch any gold, be it an enemy's drops or dungeon loot, you die instantly 100 to 0. This means that as well as the normal difficulty of the game, you have to plan around where you kill enemies to ensure that you always leave a safe path. I'm pretty confident that this is the most difficult thing I've ever done in a game. Technically 0.7% of player have the achievement, but given that 0.3% also have the achievement for completing the impossible New Game++++++++ character, we can effectively call it as 0.4% of players.

From American Truck Sim

Cornfusion Drive to the center of the Evergreen cornfield maze (requires Illinois DLC)

It says .1% of players

"Derpin' With Turpin" in Tactical Intervention.

IIRC you get this under the craziest of conditions:

• You need to snipe 2 players with 1 shot who are in a car moving at max speed while you are also in a car moving at max speed, while fully zoomed in on a sniper rifle

• One of the two developers (Turpin) has to be on the server with you

Last I checked, it had an earn rate of like 0.03%. The condition of playing with one of the actual developers of the game is what makes it super hard; not really the sniping (tho that is also super difficult). It's probably not even earnable now; I got it back when the game was still being beta tested.

Edit: Got curious and went to find the actual stats for the two rarest achievements I have according to the "rarest achievements" block on my Steam profile (cuz there is 1 even rarer than the one I mentioned above), but the data isn't accessible. The rarest one I can actually see global stats for is 2nd Dan Blackbelt for Toribash (0.8%).

0.4% Pillars of Eternity 1: No Rest for the Pro. Complete the game with fewer than 10 rests.

Ah I see witch it.

Most are DLC specific or from old games.

Red Orchestra 2

0.3%

Silent Killer

Get 32 Kills with the silenced Nagant Revolver

Man what an awesome game, I miss it

Rarest: Some random achievement in City Skylines that I didn’t even notice I got

Proudest: Embrace the Void and 112% in Hollow Knight

Factorio Express Delivery was quite an effort and a lot of fun.

I also have some fun Europa Universalis 4 achievements that were at 0.1% when I got them, but it seems that I need to up my game there :P

My top 6 rarest are 0.4% - 0.6%, all in Eternal Card Game, just because they were still adding achievements after 90% of the player base had already left.

I lost the screenshot, but i was the first one who beat crab champions on prismatic difficulty. My friend beat it a week later and was the second one. I never cared for achievements at all in video games, but seeing the 0.0% turning into 0.1% was bretty neat. It's a niche game, but i assume, just like me someone kept looking at that achievement, hoping it wouldn't flip over before they beat it.

Divinity: Original Sin 2 A friend and I managed to finish the honour run in less then 10 tries. It was awesome at the end. I played as Sebille and he as the red prince.

It's not so rare now; but on the second day Silksong was out, I got the achievement for defeating Phantom when it was still 0.1%

Heart of the machine, 0.4%

Definitely not as rare as most of y'all and probably only as rare as it is because of how many millions of people play stardew valley without ever even trying the arcade machines.

Back when RDR2 was fresh on PC, dinked around once with the death match modes and never again lol.

My rarest achievement is from The Long Dark (Finely Tuned) at 0.1%. But that's because not many people played the last episode when it came out.

My most memorable is from Titanfall 2 (...Becomes the Master) Place in the top 3 of the Gauntlet scoreboard. That one is at 2.9%

new one from an update in March, so will probably drift down the list:

long-term rarest:

all my remaining rarest ones are from Civ 5, I guess most players don't have the DLC

Not extremely rare but this achievement almost me rage-quit.

I have the "Edward Kelly" achievement in Kingdom Come Deliverance due to brewing 15 types of potions. Only 3.3% of players have it, which is pretty high compared to most of the ones posted here, but it's still a little interesting. Brewing potions in the game is a bit boring, and you can easily buy all the ones you need, so it's understandable why few people would get it. I just kinda decided one day I wanted to get to auto-brew level of skill and that meant lots of potion. Might as well make as many different kinds as I can, and auto-brew requires you've done it once already anyway.

Finished Hollow Knight 100% in Steel Soul. I don't typically chase achievements. I knew finishing Steel Soul was one, but didn't know if 100% would be another.

This one, and the same achivement on American Truck Simulator.

My two rarest achievements are for playing the objective in certain Lawbreakers gamemodes. I imagine these weren't intended to be ultra-rare but fate had other plans.

There are now third party servers to play on but they can't unlock steam achievements
