What's your rarest achievements?

Easy topic. What are your top 5 rarest achievements?

Mine are: (Game - Achievement - What it required - % of other duders that also got it)

1) Marathon Durandal - Pfhor the Win - Beat the Game - 3.3%

2) RAGE - Obsessive Compulsive - Beat the game with 100% of items collected - 4.2%

3) Marathon Durandal - 11th Clan of the S'Pht - Completed The Citadel - 4.4%

4) RAGE - Gotta Have 'em All - Collect all playing cards in one playthrough - 5.3%

5) RAGE - RAGE Nightmare - Complete the game on hardest difficulty - 5.7%

Yeah, all of mine are from the same two games. Kind of annoying.

(If you go to your achievements and hover the mouse over "Sort by achievements", you can have it sort by rarity. To get percentage, just click on the achievement)

EDIT: Shit. It should be "What are your rarest achievements?"

I have very few achievements, but I did S-rank The Binding Of Isaac so there's that.

The Binding Of Isaac - Golden God - 100% the game - 2.0%

Can't find my top 5 since I don't have my account hooked up, but I think my rarest would be:

Game Room - My Blisters have Blisters! (5 points) - Played a single game for 1 hour continuously - 1.6%

This MIGHT be somewhat out of date, none of my trophies/achievements have really updated since February.

		Sellout Spent 250,000 fans - any mode	Brütal Legend Nov. 11, 2009

Death From Above: 1.6%

1) Audiosurf - Brutus - Dethrone a friend from a global scoreboard - 4.1%

I'm actually surprised that any of these are rare as they're all absurdly easy. The first two being rare just proves that people don't use too many of Audiosurf's social features.

@Animasta: How many controllers did you go through for Been There1?

My 42 rarest achievements are all for either Football Manager 2010 or Football Manager 2012, my rarest from a game that people on here actually play is The Endless Setlist III from Rock Band 3 (4.7% have it). And my actual 5?

		French Hero You achieved promotion from the lowest to the highest league in France	Football Manager 2010 Oct. 24, 2011
		English Hero You achieved promotion from the lowest to the highest league in England	Football Manager 2010 July 15, 2010

		Part Of The Furniture You have stayed at one club for 10 seasons	Football Manager 2010 Aug. 3, 2010

That's 0.1% (5 out of 3,347), 0.1% (5), 0.2% (7), 0.2% (7) & 0.3% (11)

I might be shite at most games, but I'm pretty reasonable at the FM series, truth be told.

Fangs of the Father

Wielder of the Fangs of the Father.

Apparently my rarest. Lol. A shit ton of my WoW achievements are super rare, but I don't really think getting Legendary daggers counts since the quest chain for them was boring and more of a time sink than any sort of real achievement. Here is a better one from WoW that I am actually proud of having.

Mountain o' Mounts (10 points)

Obtain 100 mounts.

I technically got this one years ago, but getting rid of my WoW account meant getting rid of it. I rebuilt my entire collection from scratch and loved every second of it. I am an avid mount collector in the game and currently have every single mount (except for 2) that I can get by myself. Hopefully next expansion I will be able to get a few more of the ones I can't currently solo...

Anyway... if we're talking about not WoW video games it looks like my rarest is...

Down to Earth (20 points)

Executed a 20-hit down combo.

Which isn't surprising. Not many people made it very far into Infinite Undiscovery and even less people went after achievements in the game. Getting a 20 hit combo was not an easy task and took a specific enemy + a lot of luck on my party AI not being horrible (protip though, they are horrible).

Lastly the rarest one I have that I am the most proud of is this lovely one:

Adamant Will (30 points)

Felled a heavyweight of the lowerworld wilds.

These guys are the "hardest" enemies in Final Fantasy XIII. Personally I didn't find them to be the hardest enemies in the game but they certainly required the most endurance because they constantly force you to change Paradigms like crazy while also having insane amounts of HP. My fight with them took 11 minutes and I felt exhausted after fighting it, it was an intense experience.

I feel like I kinda cheat on the rare achievement thing anyway alot of he games I play are rare in and of themselves. 

		Classassin0 Get one or more kills as all nine classes in one round.	Team Fortress 2 Dec. 16, 2011
		Silver Lining0 Defeat the Undead Hero, Nimbus	Champions Online June 26, 2011
		Desert History: Project Stein0 While PRIMUS’ Project Greenskin is working to understand and ultimately contain the threat of the mutated monster known as Grond, VIPER is trying manufacture more of these genetic monstrosities. Project Stein, led by one of VIPER’s lead scientists, Dr. Timothy Blank, is devoted to making a radioactive serum that will create super-strong but slightly more intelligent Grond-like creations, ones that will be loyal to VIPER. Once Blank’s serum is perfected, it will be loaded into missiles and launched across the world, where explosive fallout will send a radioactive bacterial agent into the atmosphere-- and create an VIPER-controlled army of Gronds!	Champions Online June 21, 2011
		Hojo Victory0 Win a campaign as the Hojo clan.	Total War: Shogun 2 Dec. 25, 2011
		Dead Heat0 Play through a back-and-forth battle for 15 control point captures.	Team Fortress 2 Dec. 16, 2011

So, 2 TF2 ones, 2 Champions online, and 1 shogun 2. For the most part, only the TF2 ones are really rare, the other ones are just for games that a lot of people didn't play (or play that way)

Well if anyone wants more of these rare achievements, just about all of them in Monster Madness Battle for Suburbia are rare (for obvious reasons as the game isn't that great).

Here's a few that I know of in all the games I've played:

(skylanders) One for all

(just cause2) Trying everything once ... can't recall where online but an interactive map is out there showing the different vehicles helped so much with this one as it took forever

(marvel ultimate alliance2) Every trick in the book

(marvel ultimate alliance) Doppelgänger ... lots of easy ones too with the additional characters from the gold version of the game

(bayonetta) The ice witch

Axe Master (Complete All Tomahawk Challenges In Single Player) 2.6%

Yakuza 3: Pro Gamer (Complete trophy conditions for the games in the arcade. Get 10 stuffed animals in UFO Catcher, and get a high score in the shooting game.) 4.9%

Rock Band 2: Vinyl Artist (Finished the Endless Setlist 2 in World Tour on Medium (I did this on drums btw, I was completely worn out by the end)) 5.6%

Clothes To the Edge (Bought over $100,000 worth of items from the Rock Shop) 9.1%

Dungeons of Dredmor: Tom Marvolo Riddle Award For Scholastic Merit (Master the Magic Training Skill Tree.) 6.2%

Winter Voices: Ghost In the Cell (Leave the Seid after completing the Difficult Path.) 9.1%

Mass Effect: Extreme Power Gamer (60th level character) 9.8%

Brutal Legend: Voices From Beyond (Unlock all songs in the Mouth of Metal) 9.9%

also, I s-ranked Assassin's Creed II, and I used to have the Mass Effect 2 s-rank before Arrival came out.

None of mine are very rare it seems. I had to go to xbox exclusive and then filter by rarity. I have my WoW account linked and I guess not very many people here play or have theirs sync'd since I had to go through pages and pages of WoW achievements to find a non WoW one.

1) Maverick Goose (10 points) - Saints Row 2 - 161/10923 (1.5%)
