If you’re trying to 100% KLETKA, here’s the honest truth: most achievements aren’t hard — they’re either RNG-based or tied to smart difficulty settings.
This guide isn’t just a list. Think of it like a roadmap so you don’t waste dozens of runs figuring things out the hard way.
Because yes… this game absolutely loves random floors.
Before You Start
There’s one thing that makes achievement hunting dramatically easier.
Use Custom Difficulty settings.
Many achievements become 10× faster if you:
Maximize good settings (loot, damage, spawns)
Minimize bad settings (enemy damage, hazards)
Almost every grind achievement in this game is designed around that system.
So don’t torture yourself playing normally when hunting achievements.
First Achievements You’ll Unlock Naturally
Some achievements will happen without trying.
Start your first descent — you’ll get your first achievement immediately.
Breaking crates comes naturally while looting, but if you want to rush it, max player damage so crates break in one hit.
You’ll also unlock bottle-related achievements simply by playing and spending currency in shops.
These early achievements require almost no strategy.
RNG Floor Achievements
This category will test your patience more than skill.
Certain achievements require finding special floors marked with an exclamation icon.
Examples include:
Flood curse floors
Belmo curse floors
Matrix reference room
Party floor
Ronin Plus knife floor
These can take a long time because they spawn randomly.
The best way to farm them is Endless Mode.
Set good difficulty settings, loot early floors, then quickly descend while checking marked floors only.
Trying to brute force these in normal runs will take forever.
Companion, Item, and Collection Achievements
These achievements revolve around gathering items over time.
You’ll need to:
Collect all companion types
Spend large amounts of bottles
Find specific items like mushrooms and bags
These don’t need to be done in one run.
The easiest method is simple: maximize item spawn rates in custom difficulty.
Once you do that, these achievements become very quick.
Progression Achievements
Some achievements require reaching deep game stages.
For example, reaching the Meat Mines biome requires progressing through the Heart of Gigakhrush mode.
Another involves descending 50 floors while carrying a rat.
These aren’t difficult mechanically — they just require consistent survival.
Upgrading your Cage systems early makes these much easier.
Fuel tank upgrades are especially important for long-run achievements.
Co-Op and Social Achievements
A few achievements depend on other players.
You’ll need to:
Revive an ally using the beer machine
Gain respect from other players
Get killed by teammates in specific ways
These are easiest to complete with friends rather than random lobbies.
Public matchmaking can be unpredictable, so coordination helps a lot.
Funny Death Achievements
Some achievements are literally about dying in weird ways.
Examples include:
Stepping on mines
Getting crushed by doors
Being killed by toxic gas skills
These are intentionally silly and very easy once you know what triggers them.
Most players unlock these accidentally while exploring.
Skill Challenge Achievements
A small number of achievements actually require gameplay skill.
One notable example is completing the main mode without using a flashlight.
Another is finishing the game on Hardcore difficulty.
These require preparation more than reflexes.
Stock supplies early, play cautiously, and don’t rush floors.
Greenhouse Sector Special Achievements
Several achievements revolve around this specific biome.
You’ll need to:
Use the Scum Machine
Destroy Hogweed plants
Shoot down a flying plane
These are easiest when you force the biome to appear early using custom settings.
Without doing that, you may wait many runs just to see the area.
Boss Achievements
Boss achievements are straightforward: defeat each boss at least once.
Bosses appear at fixed floor intervals depending on the mode.
Each boss has a small trick:
Some require destroying weak points
Some require melee instead of guns
Some rely on environmental items
Maximizing player damage makes these fights dramatically easier.
The Fastest Path to 100% Completion
If you want efficiency, here’s the smartest order:
First, complete natural progression achievements while learning the game.
Second, use custom difficulty to grind collection and RNG achievements.
Third, focus on biome-specific and co-op achievements.
Finally, finish boss fights and Hardcore completion.
Following this order prevents unnecessary grinding.
KLETKA’s achievement system isn’t about difficulty — it’s about knowledge and preparation.
Once you understand how custom difficulty and RNG floors work, most achievements become surprisingly manageable.
The biggest enemy isn’t monsters… it’s randomness.
