Achievement hunting on Steam is serious business. While Valve's storefront might not have Xbox's Gamerscore or PlayStation's Trophies, there are still plenty of PC gamers who appreciate the way Steam achievements challenge them to play games in new and interesting ways. Then there's the satisfaction of knowing you're one of just a small percentage of players who've explored every nook and cranny, maxed out every stat, or earned every gold medal a game has to offer.

The thing is, a lot of Steam achievements are kind of boring. Kill 10,000 enemies, hit level 99 in every class, finish the game on Ultra Nightmare Hardcore difficulty—most of the objectives feel like they've fallen straight out of a free-to-play MMO's quest log. Even the rarest achievements are often little more than tedious grind fests, requiring you to play 500 online matches in a multiplayer game with no active player base, or fight alongside a game's developer when that developer has long ago moved onto their next project.

These achievements aren't particularly fun to earn, let alone read about. But buried in Steam's massive catalog of games are some truly obscure, brutally difficult achievements that less than 0.1 percent of players have managed to accomplish. These are achievements worthy of the name. Most of us will never earn them, but we can dream.

Devil Daggers

Devil Dagger - Survive 500 seconds

Total Owners: 236,000

Completion Percentage: 0.1

For something you could complete in the downtime between Dota matches, frantic FPS Devil Dagger's one and only achievement has managed to defy 99.9 percent of players for well over a year now. That might seem odd given how simple its requirement sounds: all you have to do is survive for 500 seconds. I mean, I do that all the time. See. That last 500 seconds? I just survived that.

But yeah. Surviving Devil Daggers is a wee bit tougher than running out the clock in real life. Despite the game selling for a mere fiver, just 0.1 percent of players have managed to avoid croaking for the 8 minutes and 20 seconds necessary to snag the 'Devil Dagger' achievement. Watching replays of those runs is equal parts mesmerizing and depressing, making it painfully clear just how amateur my own skills are. I could probably spend the next year playing nothing but Devil Daggers and still not come close to the graceful death-dealing of players like the world-record-smashing bowsr. When the apocalypse hits and the whole world goes to hell, I'll be the redshirt incinerated in the first ten seconds.

Crusader Kings 2

Not so Bad - Survive the End Times

Total Owners: 1.4 million

Completion Percentage: 0.1

Crusader Kings 2, champion of the grand strategy genre, is full of intricate, multi-layered achievements few players have managed to unlock. From installing a female ruler in the five baronies of the Orthodox Pentarchy, to trampling the Pope with a horde of elephants, over a dozen eclectic achievements are currently sitting at a completion rate of less than 0.1 percent.

The one I want to shout out, though, is the 'Not so Bad' achievement awarded for surviving the End Times. Ostensibly, you unlock this achievement by surviving the rise of the Prophet of Doom and the Black Death he's convinced will destroy humanity. A Crusader Kings player going by the username Xolotl123 on Reddit, however, inadvertently earned themselves the achievement due to their investment in high-quality hospital care and their imprisonment of the Prophet for disturbing the peace. The Prophet then hanged himself, but not before sending the player a letter that read: 'If you are reading this letter, I am with God, or with Lucifer..., if so, then you were right. If not, then I was right.'

I've not had the time to play Crusader Kings 2, but after reading this story, I think I'm going to have to clear my schedule. Any game where you can avert the End Times through hygiene is a winner in my book.

Rising Storm / Red Orchestra 2

Bringing a sword to a sword fight – As an American soldier kill an Axis soldier wielding a Katana, with a Katana.

Stick it to Tojo – As an Allied soldier, kill 100 Axis soldiers with a bayonet.

Total Owners: 2.7 million (unreliable due to free weekend)

Completion percentage: 0.1 - 0.2

Rising Storm's focus on historically authentic, asymmetrical WWII combat means that, naturally, American soldiers do not spawn into the battlefield with katanas. In order to get one, you have to defeat a Japanese soldier who's carrying one. And in order to get the "Bringing a sword..." achievement, you then have to pick up their katana, find another Japanese soldier with a katana, and then defeat them with the weapon of their ancestors. It's a hard scenario to concoct in an FPS where rifles and grenades are the preferred way to fight.

Bit.Trip Beat

MEAT.BOY SMELLS - Get a perfect in 1-1 using only a game pad.

Total Owners: 311,00

Achievement percentage: 1.6

Heresy! An achievement that requires ditching the holy mouse and keyboard for a filthy gamepad? What does BIT.TRIP BEAT take us for, console players? Everyone knows a good M+K combo is the only way to play. Sure, it makes driving games a bit twitchy, and performing combos in third-person action games can be tricky without analogue sticks, and fighting games don't always work so great, and stealth sequences tend to be a little wonky with WASD…

Okay. So maybe gamepads aren't that bad. Still, locking an achievement to a specific piece of hardware is a surefire way to tick off achievement hunters. The BIT.TRIP devs found that out the hard way with the game's 'SIXTH.SENSE' achievement , which required players to beat a level using Razer's short-lived Sixense motion controller. The backlash to 'SIXTH.SENSE' drove the devs to delete the achievement from Steam completely, which technically makes it one of the rarest achievements out there. Not quite as rare as a game with motion controls that don't feel like total garbage, but still…

The Stanley Parable

Go outside - Don't play The Stanley Parable for five years

Total Owners: 2.1 million

Number of achievers: 2 verified through AStats (6.9 percent on Steam)

Games are meant to be played—we usually take that much for granted. It's a little odd, then, when a game actively encourages you not to play it. Odd, however, is what The Stanley Parable's all about. I mean, one of the game's endings involves running back and forth between two buttons for four hours. And that's not to mention the pointed commentary on the nature of free will and the human tendency towards obeisance. Like I said, odd.

The Stanley Parable's weirdest elements, however, are definitely its achievements. In addition to an achievement simply entitled 'Unachievable' (paradoxically earned by 3.9 percent of players), there's the 'Go outside' achievement that tasks players with not playing the game for five years straight. Since The Stanley Parable released in October 2013, no one can legitimately earn this achievement until October next year. Of course, that hasn't stopped some unscrupulous Steam users from setting their computer clocks forward to unlock the achievement early.

Cheating to not play a game? I guess some people will do anything for their sweet cheevos.

Garry's Mod

Addict - You have wasted a year of your life playing GMod!

Total Owners: 13.2 million

Number of achievers: 9 verified on AStats (1.8 percent on Steam)

You can do a lot of things in the 8760 hours that make up a single year. You could play 105,120 matches of Rocket League. You could marathon the entire current run of The Simpsons—all 617 episodes—38 times over. You could hitch a ride on a rocket and fly to Mars, with enough time left over to plant the seeds of an interplanetary rebellion.

You could also spend every one of those 8760 hours playing Garry's Mod in order to unlock the 'Addict' achievement. And when I say playing, I don't just mean booting up the game and letting it idle in the menu. You have to be connected to an active server for your time to count. Unsurprisingly, the hefty investment involved has kept the achievement's completion percentage at just 1.8 percent, even with achievement hunters over at AStats devising strategies for minimizing the resources used by Garry's Mod so you can leave it running in the background while you tend to other tasks.

I have to wonder, though, how many people left their computers on while they were working or sleeping solely to unlock this achievement? At a modest estimate, 8760 hours' worth of electricity would cost roughly $210 USD, which is a whole lot of money for a single achievement. Kind of puts all those pesky microtransactions to shame, doesn't it?

Train Simulator

DLC scenarios

Total Owners: 995,000

Completion percentage: 0

Speaking of money, Train Simulator boasts some of the rarest achievements on Steam, but that's not because they're brutally difficult or stubbornly obscure. Heck, the achievement descriptions make it pretty obvious what you've got to do: the 'It Works For Dogs!' achievement reads 'Awarded for completing scenario [RailfanMode] Barking. It's not like the game's unpopular either, with nearly a million owners on Steam and a median playtime of a respectable 7.5 hours.

No, what makes Train Simulator's achievements so rare is that fiendish friend of ours: DLC. Train Simulator is notorious for having the most expensive DLC on Steam, with its total value currently sitting at $6254.43 USD. Worse, Train Simulator ties many of its achievements to its DLC, leading to a wealth of 0 percent and 0.1 percent completion rates across the board.

But that $6254.43? I'd want a real honest-to-god train if I was forking over that much cash. If it was anything like Train Simulator, though, it'd probably lock out the train whistle as premium DLC. Steam whistle: only $0.99 per toot!

Ark: Survival Evolved

Artifact Archaeologist – You personally retrieved all Eight Artifacts!

Total Owners: 4.7 million

Completion Percentage: 0.2

A whole lot of people play ARK: Survival Evolved, and yet even the most common of its seven achievements has been earned by less than 5 percent of players. But while 95 percent of ARK players haven't defeated the game's first Ultimate Life Form, 99.8 percent remain vexed by its toughest achievement: 'Artifact Archaeologist', rewarded for retrieving every Artifact in the game. It sounds simple enough, but this is where ARK's nature as an Early Access game comes back to bite it on the rump.

According to the achievement description, there are only eight artifacts in ARK: Survival Evolved. This isn't true. There are 14 artifacts in total, 10 of which can be obtained through normal play, 3 which are locked to the Scorched Earth DLC, and one which can only be spawned through a console command. For a game that has already seen its fair share of controversy, ARK has left quite a few achievement hunters pretty disappointed. Still, at least they can take solace in the giant bees that have just been added to the game. That's something, right?

The Elder Scrolls V: Skyrim

Dragonrider - Tame and ride 5 dragons

Total Owners: 11 million (unreliable due to free weekend)

Completion percentage: 0.8

I'm going to go out on a limb here and assume you've played Skyrim, or at least heard enough about it to understand the game's premise. You're the dragonborn, you need to save the world from an evil dragon, yada yada yada. In short, the game basically revolves around dragons.

How, then, is the achievement for riding dragons so rare? Only 0.8 percent of the millions of Skyrim players have tamed five or more of the mythical creatures and taken to the skies, which makes exactly zero sense to me. Who wouldn't want a dragon as their personal chauffeur? It's not like you'd have to worry about anyone jacking your scaly pal; any thief foolish enough to try would be charred to a crisp before they could shout Fus Ro Dah. I guess Skyrim players are just too busy getting busy and fighting Macho Man Randy Savage to spend their time becoming certified dragon pilots.

Black Mesa

Rare Specimen – Send the Hidden Hat to Xen.

Total Owners: 500,000

Completion percentage: 2.1 percent

Hats are all the rage these days. I have it on good authority from my stock broker that the hat economy is only going to go up—and that's coming from a man who wears a top hat, so you know it's legit. My wardrobe is already full of baseball caps, bowler hats, fezes, and beanies, just waiting for the day when my fabric fortune will be ready to claim. The only thing I don't quite understand is why my broker keeps mentioning Dota. Eh, never mind. I'm sure it's nothing.

Video games, it turns out, are just as keen to cash in on the hat craze. Black Mesa, the fan-made recreation of the original Half-Life, adds in the 'Rare Specimen' achievement that tasks good old Gordon Freeman with locating a hidden purple top hat and lugging it all the way from the Black Mesa Research Facility on Earth to the alien dimension of Xen. It might not sound that tricky, but apparently Gordon's more interested in trivial things like saving the world instead of securing his future in the hat economy--only 2.1 percent of players have carried the top hat all the way to its new interdimensional marketplace.

Wait, that gives me an idea. What if I started selling digital hats instead of physical ones? Ooh, I think I'm onto something here. I better stop typing before someone beats me to the punch…
