Games

Somehow I'm among the 6.1% of Stanley Parable players with this one.

I don't have it on Steam yet, but I have Balatro's Completionist++ on mobile.

I'm working on getting it on Steam too. Once you've done it once, getting it again isn't hard, just time-consuming. It's a 0.2% achievement, I think.

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.

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.

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.

Not as rare as some others, but takes a little while to achieve:

Oh Nosgoth, we hardly knew ye...

Not at all an achievement hunter, and Steam is not my default gaming platform...

But I checked my rarest achivements and I've got a 1.4%. Which does not sound much, except it's in fucking Skyrim, and absolutely trivial to get.

OK, there's the catch : it's because this is Skyrim VR. It's the achievement you get just for mining ore and chopping wood.

Looks like there are some relatively easy .3/.4% to get there if you've got a VR headset and some dedication. And manege to keep the game working long enough to get those. That might be the hardest part, because ... Bethesda.

From American Truck Sim

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

It says .1% of players

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

Close to my rarest, but very fun and surprisingly strong! From Victoria 3

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

This thread is a self doxxing minefield

"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%).

What about the inverse?

I got Satisfactory before the 1.0 release. I played most of the game before achievements were added. Now the achievement for "reaching the credits" is achieved but "finish the tutorial" is still waiting to be done.

It's not an achievement, but this is pretty rare

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

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

I'm this many years old on Steam and don't know how to find my achievements on the mobile app.

Watch_Dogs, 0.2% achievement

3.1% of players for Dungeons of Dredmor

My sibling, why would you ever play witch it on an official server?

Rarest

Proudest (Love this game, highly recommend)

0.4%

Not as low as some other percentages in this thread but I was very proud to beat the last pantheon in Hollow Knight. You have to beat every boss in the game in a row without dying

this is a free game, but I don't think there are a lot of people who have played it (delivery & beyond).

otherwise it'd be these for tabletop simulator

Shadows of Doubt. These achievements are not rare because they are difficult, but because they are tedious. Most of the ones listed here are just repeatedly eating a food item, which costs almost nothing (1200 credits for solving a typical case, 700 for an easy case; 12 credits to buy a Croque Monsieur, the most expensive food in the game.)

Rat Catcher: Solve a murder while your PoV is at the ground, but you can crawl up walls, and also nobody will talk to you. This achievement is rare mostly because this game mode was added a few years after this game peaked in popularity.

Spare No One: KO everyone in town, in a game where you are discouraged from using violence. Finding a katana and knocking out everyone you see on the street is easy enough. The real challenge here is keeping track of everyone. Some NPCs glitch out and get stuck in their houses, never go outside, and never come to work. You'll have to identify them, find out where they live, and hunt them down. Some NPCs have accented characters in their names, making them difficult to search for on the computers in game, which do not allow you to type such characters.

If you make a case board to keep track of everyone, the case board takes exponentially increasing time to open for each person you pin onto it. By the end, it was taking me about 5 seconds each time I opened it. That was in a custom procedurally generated town of the smallest possible size -- it would be worse on any of the stock towns.

Out of the Red: pay off 10,000 to a loan shark in 1,000 credit increments, one payment per day. Raising 10,000 can be done in half a day easily. Paying it off takes for ever. You can't make payments early. Each one-day wait takes a few minutes, since the game has to simulate every NPC in town. And remember to turn off the procedurally generated murders, because otherwise your loan shark might get killed, and you can't make payments any more (it happened to me, and I had to load a save.)

What game is that?? Ive done something similar in Gamble With Your Friends but there's no achievement for that in the game XD
