Shift At Midnight ships with ten Steam achievements. Seven come with a description telling you exactly what to do. Three come with nothing but a name. This page lists all ten in the order the playerbase actually earns them, with the global unlock rate beside each, and separates what Steam states from what other guides have filled in around it.
The first thing almost everyone does. It carries no condition about being right — the game does not check whether the person you shot was a doppelganger, and neither does this achievement. Its unlock rate is the most useful number on this page for a reason given below.

A Hunt is what the game calls the state that begins when something you let through comes back for you. The wording is worth noting — surviving is the condition, not winning, and the gap between this number and First Blood is only three points, so nearly everyone who plays at all reaches one and lives.

The first of three achievements that name an enemy type. A Shrieking Doll is the most commonly killed of the three by a wide margin, which places it early, common, or both.

Ten points rarer than the Shrieking Doll and still earned by four owners in five. Nothing the developer has published describes what a Demented is or where it appears; the achievement text is the only first-party place the word occurs.

The first real wall, and the only achievement on the list that asks for speed. It sits 34 points below the achievement above it, which is by some distance the largest gap anywhere in the ten. This is a skill condition rather than a progress one, which is what makes it the cleanest difficulty marker in the set.

Rarer than the thirty-second Hunt, which is the surprise here. The Marionette is the one enemy on this list the developer has referred to directly — a day-one patch note records its health being lowered — so the low rate is more likely to be about how seldom you meet one than about how hard it is to kill.

Hidden, and yet held by roughly a third of owners — more of them than hold Locked And Loaded, which is fully described. Whatever it asks for, it is not the hardest thing on this list, and the name is the only clue Steam offers.

The hardest of the seven described achievements, and the only one that is bought rather than earned. It asks for a complete melee collection and a filled arsenal, which makes it a money problem across many shifts rather than anything you can attempt tonight.

The only hidden achievement whose name states what it is. The game has multiple endings, so this one marks a specific resolution rather than simply finishing. Steam publishes no requirement for it and neither does the developer.

The rarest achievement in the game, held by fewer than one owner in ten. Hidden, unexplained, and not obviously an ending despite frequently being listed as one. Nothing first-party connects it to anything, which is worth saying plainly rather than filling in.

A global unlock rate is the share of everyone who owns the game that holds a given achievement. On most games that number is a poor difficulty signal, because it is dragged down by people who bought the game and never launched it, and there is no way to tell how many of those there are.
Here there is. First Blood asks only that you kill a customer, and 96.5% of owners have it. So the population that bought this and never really played it is somewhere under four percent. That is small enough that the rest of the column can be read close to face value — when Relentless sits at 44.8%, that is roughly “fewer than half the people who played this managed it”, not an artefact of dormant library entries.
That calibration is the reason this page leads with the rates rather than burying them. They are the only numbers about these achievements that anybody outside the studio can check.
The intuitive reading of a hidden achievement is that it guards something difficult. The data says otherwise here.
Grave Decision is hidden and sits at 32.2%. Locked And Loaded is fully described and sits at 23.2%. A third of owners have stumbled into the secret one; fewer than a quarter have finished the shopping list. Hiding an achievement is a decision about spoilers, not about difficulty, and on this game the two come apart clearly enough to see.
The practical consequence for anyone going for completion: the achievement that will take you longest is the one whose requirements you already know. Locked And Loaded needs a complete melee collection and a filled arsenal, and that is an income problem measured in shifts. Nothing about it is hard in the moment.
Grave Decision, True Ending and Empty Home have names, unlock rates and empty description fields. This is not a gap in our research — the fields are blank on Steam’s own achievement list, which is the same page Valve serves to everyone.
Only one of the three names itself. True Ending says what it is, and since a run can resolve in more than one way, it marks a particular resolution rather than a completion. That much is safe.
The other two are where other pages start inventing. Grave Decision reads like a choice and Empty Home reads like an outcome, and both readings are guesses about English rather than findings about the game. They get listed as ending achievements fairly often; we have found nothing first-party that says Empty Home is an ending at all, and at 9.8% it is rarer than the achievement that openly calls itself one — which is at least a reason to hold the assumption loosely.
If you have unlocked any of the three, the pop tells you what you had just done. That is currently the only reliable source that exists for them.
Something worth extracting from the descriptions, because it is the only place the game states these names in writing:
The store description talks about doppelgangers and about the thing that arrives when one gets past you, and it names none of these three. Across all twenty-seven of the developer’s Steam posts only one of the three appears at all. The achievement list carries all three, which makes it a small piece of first-party bestiary hiding in a menu most people scroll past.
That one exception is the Marionette: the day-one patch of 23 July 2026 lists “Lowered Marionette HP” among its changes. That tells us it is a fight with a health pool substantial enough to need balancing, and that its 40.7% is measured against a version that is easier than launch day. Read alongside the end-of-shift sequence a mistake triggers, the ordering of these three rates is the closest thing available to a threat table. What that single patch line does and does not establish is separated out in what is actually known about the Marionette.
The game is built for one to three players — the developer’s own day-one note says it “has always been marketed around a maximum of 3 players” while adding a lobby option up to six, with a warning that anything above three is outside the design.
What nobody has published is how the kill achievements attribute in a shared lobby. The wording is second person throughout, and Survive Your First Hunt is necessarily individual because surviving is. Whether Kill a Marionette requires your bullet or merely your presence is not stated anywhere we can find, and the guides that answer it confidently do not show their working.
This is cheap to settle for yourself and expensive to guess at: play a session where somebody else takes the kill, then look at your own list. One run answers it properly for your build of the game, which is more than any page can promise.
Every name, description and percentage here was read off Steam’s achievement list for the game on 8 August 2026, and the count was cross-checked against the store page’s own “Includes 10 Steam Achievements” line. The three blank descriptions are blank at the source.
Unlock rates move. They drift downward as a game keeps selling to people who play less of it, so treat these as a snapshot with a date on it rather than a constant — the ordering is far more durable than the individual figures.
Nothing on this page describes how to unlock Grave Decision, True Ending or Empty Home, because no first-party source describes it and the customers and doppelgangers on file do not hint at it either. When that changes, this page changes.
Ten. The Steam store page states "Includes 10 Steam Achievements" and the game's achievement list shows ten entries, so the number is confirmed from two places on Steam rather than counted off a guide. Seven of the ten carry a public description; three carry only a name.
Grave Decision, True Ending and Empty Home. Steam shows their names and their global unlock rates but publishes no description for any of them, and the developer has never written about them either. Any page giving you step-by-step requirements for these three is telling you something it cannot source.
Empty Home, held by 9.8 percent of owners. True Ending is next at 15.6 percent, then Locked And Loaded at 23.2 percent. Empty Home is rarer than either of the two achievements most people assume are the hardest, and nothing published explains what it asks for.
Buy every melee weapon and fill out the weapons arsenal — that is the achievement's own wording, and it is the only fully described achievement that money rather than skill unlocks. At 23.2 percent it is the rarest of the seven described ones, which fits a requirement spread across many shifts of earnings rather than one good night.
Nobody has published a rule, so treat any confident answer with suspicion. What can be observed is that the wording is second person throughout — Kill Your First Customer, Survive Your First Hunt — and that surviving is necessarily individual. If you want to know how the kill achievements behave in a lobby, the cheap test is to check your own list after a session where a teammate took the kill.
An enemy, and the only one of the three named in the achievement list that the developer has mentioned independently — the day-one patch on 23 July 2026 lowered its health. Killing one unlocks Last Performance, held by 40.7 percent of owners, which makes it rarer than the thirty-second Hunt challenge.
