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.

Oh Nosgoth, we hardly knew ye…

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

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

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

From American Truck Sim

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

It says .1% of players

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.

3.1% of players for Dungeons of Dredmor

“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.

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

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
