All 11 Achievements With Steam Unlock Rates
Every Sir, We Have an Orc Problem achievement with its real global unlock rate from Steam, and which level players clear each challenge on.
Orc Problem 3.2: Why Difficulty Suddenly Spikes
3.2 is where most players hit a wall. The cause is which upgrade branches you took, not how you place turrets, and it is fixable before you get there.
Orc Problem 6.1: The Four
Only 10.8% of players clear a level with four turret types and no abilities. Three player-written 6.1 layouts, including one without slow grenades.
Orc Problem 6.2: The Damageless Run Explained
6.2 is the last level, and the damageless clear is not an achievement — it is a community challenge. What the most-read guide on the game actually contains.
The No
20.1% of players have cleared a level without placing a turret. What the four abilities do, and why this achievement is really an upgrade check.
Levels are numbered, and the numbers matter
Levels use an X.Y format — 1.1, 2.1, 3.1 and so on up through 6.2. That numbering is what players search for, and it is how the community organises its layouts: a guide titled "6.1 4-Tower only" is telling you both the level and the constraint.
The game has 11 achievements, and Steam publishes the global unlock rate for each one. That rate is the most honest difficulty curve available, because it is measured rather than opinion. Three of the eleven are progression markers; the other eight are self-imposed constraints.
The difficulty curve, measured
Surviving the first level sits at 97.3% — effectively everyone who launches the game. Surviving the third is at 87.7%. Then it falls off a cliff: surviving the sixth is at 26.9%.
The constraint achievements sit lower still. Clearing a level with only four turret types is the rarest in the game at 10.8%, below even the three-type version at 15.6%. That inversion is worth pausing on — using more turret types is harder, because the achievement forbids abilities and forces you to hold every lane with turret placement alone.
Which level each challenge is done on
A guide by the Steam user itsuno, posted 29 July 2026 and read by roughly 4,900 people, maps each constraint achievement to the level they cleared it on: single turret on 1.1, no turrets at all on 2.1, one turret type on 3.1, the flamethrower/tesla/cryo combination on 4.1, three types on 5.1 and four types on 6.1.
We are repeating that as where one player did it, not as a requirement the game states. Whether the achievement is level-locked or simply easiest there is not documented anywhere we can point at.
The two hardest ones have published layouts
Level 6.1 with only four turret types has at least three player-written layouts, and they disagree in an instructive way. One build leans on slow-down grenades; another player, Григорий, explicitly wrote his because every walkthrough he found required grenades he had not unlocked, and solved it with freeze-beam discipline and constant pausing instead.
If you are stuck on a layout, the useful question is usually which upgrade branch it silently assumes you have.
What is not here
No wave-by-wave enemy tables and no complete level list past 6.2. Neither exists in any source we can verify. We also do not reproduce the save-file editing method some guides describe — it works, but a corrupted save costs more than the grind it skips.
