Zombie Lab Walkthrough — From First Test to Extreme Trials

A Zombie Lab walkthrough is not a route through levels, because the store page publishes no chapters, missions or stage list. What it can do is lay out the order in which the documented systems come online: get a working test, learn what the results mean, then spend unlocks on experiments that go further. That is the progression the official copy describes. This page walks it in stages, and the beginner guide covers the same ground at first-hour pace.

Stage 1: Learn one complete test

The opening stage is a single lap of the loop, run end to end. The store page's feature list begins with experimenting on your zombie and testing weapons and equipment, then moves to tracking the results, so the first thing worth doing is applying one tool and reading what comes back.

• Choose one piece of equipment from the lab.
• Apply it to the undead subject.
• Read the damage, durability and recovery figures.
• Note the reading before you touch anything else.

Doing this once gives you the shape of a session. Doing it twice gives you something more useful, which is a comparison. The store page does not publish a tutorial, so how much guidance the game provides at this point is not documented yet.

Stage 2: Build a comparable baseline

The second stage is about making your readings mean something. Official text says you track damage, durability and recovery as experimental data, and a set of numbers only becomes data when you can line it up against another set. That is why the baseline comes before the unlocks.

Keep one test fixed and repeat it as you change a single variable. If damage rises while recovery time also rises, you have learned something about the trade. If you change two things at once, you have not learned which one moved the numbers. This is the least glamorous stage and the one that makes the rest of the progression readable.

Stage 3: Spend unlocks on new experiment types

Once you can read your own results, the store page's progression opens up. It says you unlock new equipment and experiments and expand your lab with increasingly extreme ways to test your zombie, and its feature heading for that is Unlock New Experiments.

The key word is experiments rather than upgrades. Nothing in the official copy describes making a single tool stronger; it describes widening what you can do to the subject. So the natural order is to take unlocks that add a new test or a new machine, because each one adds a measurement you did not have before.

Stage	What you are doing	What it unlocks
1	Run one test end to end	A working loop and a first reading
2	Repeat the same test with one change	A baseline you can compare against
3	Take new experiment unlocks	New kinds of test and new measurements
4	Push the tests further	The increasingly extreme trials the store describes

Stage 4: Push toward the extreme trials

The last documented stage is the one the store page keeps pointing at. It says you put your subject through increasingly ridiculous trials, push undead science beyond reasonable limits, and expand the lab with increasingly extreme ways to test your zombie. So the direction of travel is escalation of the tests themselves.

This is where the tone matters. The Dark Humor feature and the store line about the game not taking its science too seriously tell you how to read these trials: they are framed as absurd rather than grim, and the subject is described as something that recovers and is tested again.

What the walkthrough cannot tell you yet

Several things a walkthrough would normally cover are not documented. There is no published test count, no unlock cost, no currency, no session length and no completion state. There is also no verified update history, because no news posts were available for the app when this page was written.

That leaves the walkthrough as an order of operations rather than a checklist of objectives. If you want the mechanics behind each stage in more depth, the experiments page covers the tracked results and the unlock loop, and the tips page turns the same stages into habits.
