KLETKA Guide: How to Use Fuel Canisters & Upgrade Your Gear
As someone who’s sunk way too many runs into Kletka, I can tell you one thing with confidence: fuel management is the difference between a clean descent and a slow, screaming death in the Gigastructure. Gas Cans look simple, but misuse them and the living elevator will punish you hard.
Below is my fan-made, experience-driven breakdown of how fuel really works, what mistakes new players make, and how to stay alive longer than your sanity.
Why Fuel Is Everything in Kletka
Fuel isn’t just a resource — it’s the lifeblood of the Kletka. When the gauge hits zero, the elevator triggers an Emergency Stop, leaving you stranded on a hostile floor while the situation rapidly spirals out of control.
At zero fuel, afterburners activate automatically, damaging the fuel tank and increasing fuel consumption until the system is repaired with a wrench. In short: no fuel equals a chain reaction of problems.
Gas Cans Explained (And Why Weight Matters)
Gas Cans are the most reliable fuel source in the game, but not all cans are created equal. Their fill level affects not only how much fuel you gain, but also how heavy they are to carry.
| Fill Level | How Common | Veteran Opinion |
|---|---|---|
| 15% | Very common | Lightweight and perfect as backup fuel |
| 50% | Uncommon | Often bait for traps, approach carefully |
| 100% | Rare / Shop | Heavy but extremely valuable, save for emergencies |
Pro tip: Full canisters slow you down and count heavily against the Kletka’s weight limit. Carrying too many can get you killed when things start hunting.
The Right Way to Refuel (And the Wrong One)
There are two ways to use a Gas Can, but only one of them is efficient.
- Fuel Tank (Optimal): Interact with the red fuel tank on the left side of the elevator interior. This method gives you the full fuel value with zero loss and should be your default choice.
- The Mouth (Emergency Only): You can feed the canister directly to the Kletka. This is faster but results in a 25% fuel loss because the elevator consumes the container itself.
Rule of thumb: Mouth feeding is for panic situations, not routine refueling.
Fuel Storage and Multiplayer Factors
The Kletka includes a dedicated gas can storage rack on the right side of the elevator, allowing you to free up personal inventory space.
The number of available storage slots increases if you have three or more players in the lobby before summoning the Kletka, making cooperative runs significantly more forgiving.
Warning: Fake Souls can steal gas cans directly from the storage rack if left unattended, turning your careful planning into a disaster.
Advanced Fuel Mechanics Most Players Miss
Gas Cans cannot be stacked or merged, meaning every canister is an individual decision. On Factory floors, they can also be used to refuel stationary generators to restore lighting.
Mines are frequently hidden beneath higher-value canisters, especially 50% and 100% variants, so always check the floor before grabbing fuel.
You can upgrade the Fuel Tank using Gears, increasing maximum fuel capacity by 5 units and reducing overall consumption by 4%. These upgrades may not look exciting, but over long runs they are absolutely run-saving.
When Gas Runs Out: Alternative Fuel Sources
If Gas Cans are scarce, the Kletka will accept other forms of fuel. Organic matter such as meat harvested from bodies, slimeballs, and eyeballs can be fed directly, and liquids like beer or vodka can be poured into the fuel tank.
Risk warning: Feeding the Kletka live rats or eyeballs can make it sick, potentially spawning landmines or fly swarms inside the shaft. Sometimes survival means gambling, but know the odds.
Feeding the Elevator, Beating the Horror: A Fan’s Gear & Upgrade Guide to KLETKA
If you’ve spent more than an hour inside KLETKA, you already know one thing: skill alone won’t save you. The deeper the Gigastructure goes, the more the game becomes a brutal numbers race. Better gear, smarter upgrades, and ruthless inventory decisions are what separate a doomed run from a legendary descent.
Below is my personal, player-tested take on crafting, upgrades, and survival — written from experience, not patch notes.
1. Upgrade Priorities: What Actually Keeps You Alive
Not all upgrades are equal. Some feel useful, others are run-defining.
- Scanner (Top Priority) — This is the upgrade I rush every single run. Early levels help you avoid junk floors, while Level 4 and above turns it into a tactical weapon. Knowing loot before the elevator stops saves fuel, health, and time. A high-tier Scanner lets you plan routes instead of gambling.
- Fuel Tank — Fuel is life and inventory space. More capacity means deeper runs, around 4% fuel efficiency per level, and a passive weight bonus of roughly +5 kg per level. If you like fully clearing floors, this upgrade pays for itself fast.
- Kletka Chassis — Not flashy, but reliable. It increases elevator speed, maximum health, and repair efficiency. Important detail: Haste Gears only work here and nowhere else.
2. Personal Gear: Crafting That Actually Matters
With the Echoes Below update, gear crafting finally feels meaningful — and dangerous.
- Backpacks & Bags — Simple math with massive impact. Each upgrade adds one inventory slot, up to a maximum of nine. More slots mean more weight capacity and better movement when managed properly. This is the safest long-term investment in the game.
- Flashlights — Often underestimated. Battery capacity can be upgraded, but recharge speed never improves. Overusing light early almost always leads to panic later. Veteran tip: treat light like ammo.
| Weapon | How You Get It | Notes |
|---|---|---|
| Machete | Rare loot | Silent and deadly |
| Sgushka Gun | Rare loot | High risk, high reward |
| Enchanted Firearms | Craftable | Level 3 unlocks special projectiles |
| Liquidator’s Flamethrower | Scavenged | Extremely powerful, not craftable |
3. Cogs, Luck, and the Real Economy
Cogs are the true late-game bottleneck. They are required for high-tier upgrades, usually hidden behind cracked walls, and most reliably found by fully exploring floors and surviving past the Samosbor event if bulkhead doors are available.
The Luck stat is one of the most underrated attributes in the game. It increases item drops from breakable objects and corpses and directly affects Cog farming efficiency. Ignoring Luck in late-game builds is essentially playing on hard mode.
4. Maintenance Tools You Should Never Leave Behind
| Tool | Why It Matters |
|---|---|
| Wrench | Repairs systems and disarms explosive mines |
| Fire Extinguisher | Mandatory for Fire Floors to prevent overheating |
| Gigabooze | Instantly revives all teammates when used inside the Kletka |
5. Hard-Learned Survival Tips
- The Kletka’s mouth works as shared storage, but it will consume items if it is not properly fed.
- Stats from Tier I–III gear usually stack, while final-tier stats often replace earlier bonuses.
- Refining gear to its final tier can reduce refinement level or remove extra slots and enchantments.
- Sometimes stopping early is smarter than pushing one upgrade too far.
Final Thoughts
Fuel management in Kletka isn’t about hoarding resources, it’s about making the right decision under pressure. Do you carry the heavy full can or stay mobile? Do you pour it safely or sacrifice efficiency to survive the moment?
That tension is what makes the game work and why every drop of fuel feels earned.
KLETKA rewards players who plan instead of rushing. The game doesn’t care how brave you are — it cares how prepared you are. Master the Scanner, respect fuel math, and treat every Cog like gold. Feed the elevator properly, and it might let you live, or at least die deeper than last time.
