Your first three days

Step

In short Everything before Day 3 is preparation — once the water stops, you are living off what you already collected.

The game starts you in Apartment 3004 with limited supplies and working taps. On Day 3, the building's water, power, and phone network shut off permanently, so your first priority is filling every container you can find. After that, secure the apartment and find a weapon before you venture further.

Strip the apartment go through every drawer, shelf, and cupboard in 3004 and take everything useful.
Fill water now run the taps to fill the bathtub, buckets, Jerry Cans, and every bottle before Day 3 hits.
Board the corridor door use planks to barricade the door so infected cannot walk straight in.
Move quietly sprinting draws infected, so walk unless you have a good reason to run.
Grab a weapon the kitchen is a good first stop; anything you find is better than nothing.
Pick up a Funnel it lets you pour water from large containers into small bottles without spilling any.

Water containers and why they matter

Table

In short Bigger containers store more water but slow you down or block certain routes, so carry a mix.

Thirst drains 39 points per day — about 30 percent faster than hunger — so water runs out first. Choose containers based on what you need to carry versus what you need to store.

Container	Capacity	Key limitation
Bottle (1L)	1 litre	Small; fits in one hand
Sealed Bottle (2L)	2 litres	Must be opened before you can drink or pour
Bucket	10 litres	Two-handed carry; cannot go through vents
Jerry Can	20 litres	Heavy; best for stockpiling before the Day 3 cutoff
Funnel	Transfer tool	Moves water between containers without waste

The day and night cycle

Summary

In short Day 3 and Day 15 are the two moments that reshape the entire run.

Each in-game day lasts 600 real seconds — 450 seconds of daylight and 150 seconds of night. A full 15-day run takes about two and a half hours. You can lie down from 19:00 onward, which lets you get settled before night officially begins at 19:15.

One day　10 real minutes (450 s day, 150 s night)
Sleep window　opens at 19:00, before night starts at 19:15
Day 3　water, power, and phones cut off permanently
Day 6　rain falls, giving you a chance to refill containers
Day 15　a massive horde sweeps through the building at night
Full run　roughly 2.5 real hours at normal pace

Staying alive at night

Check

In short A barricaded door and a proper bed make the 150-second night much safer.

Night is short but infected do not stop just because you are asleep. Hunger and thirst keep draining while you sleep too. Get these things sorted before 19:00.

Reinforce the corridor door planks and screws can push it from 100 integrity up to 150.
Brace furniture against the door for an extra layer of protection.
Sleep on a mattress, bed, or sleep bag stamina recovers much faster than on the floor.
Check your food and water meters both keep draining overnight.
Watch the lock it only has 50 integrity, half that of the door, so it breaks first.

Dealing with infected

Warn

In short Being surrounded by three infected at once is extremely dangerous — retreat rather than fight.

A normal hit deals 16 damage and a heavy hit deals 28. Up to three infected can attack at the same time, so the damage stacks fast. If your food or water meter drops below 20, you also take 1 damage every 5 seconds, though that stops at 5 HP rather than killing you outright.

Worth watching out for

Use the stairs to break contact a narrow stairwell lets you face one attacker at a time instead of three.

If a teammate goes down, reviving them restores 60 percent of their health; the Medic class does it in half the time.

On Hard difficulty, infected deal 25 percent more damage and take 25 percent more hits to drop.

Classes and what they cost

Table

In short The free Survivor class can do everything — paid classes just do certain jobs faster or quieter.

You earn 10 Cash for every day you survive and a 300 Cash bonus for reaching extraction. Cash is spent in the Class menu and cannot be traded.

Class	Cost	Starting item	Main benefit
Survivor	Free	None	Baseline — all mechanics balanced around this class
Scavenger	250 Cash	1L Water Bottle	Spots missed loot and identifies containers before opening them
Trapper	250 Cash	Mesh Roll	Builds pigeon traps faster and uses half the bait
Courier	250 Cash	3 Noise Makers	Sprints for less stamina; marks shortcuts for the team
Scout	500 Cash	Flashlight (45% battery)	40% quieter while walking or crouching; opens doors silently
Porter	500 Cash	Daypack (worn)	Extra two inventory slots; half the slowdown from heavy items
Cook	500 Cash	Cooking Pot	One bonus portion per batch; uses half the stove fuel
Plumber	650 Cash	Wrench	Frees stuck valves faster; rain collectors fill slightly faster
Electrician	650 Cash	AA Batteries	Batteries last 40% longer; hand-crank charger gives 50% more power
Caretaker	900 Cash	Screwdriver	Repairs doors 40% faster; repaired doors take 15% less damage
Medic	900 Cash	2 Bandages	Bandages heal more and apply faster; revives teammates in half the time

Rooftop pigeon traps

Step

In short Once the apartment's food runs out, the roof is your only reliable source of new calories.

The starting food supply covers roughly five days at full rations. After that you need a renewable source, and pigeon traps on the roof are it. Build them on the east and west ledges, and keep noise and bright lights away from the area or the flock will scatter.

Gather materials you need Planks for the base, a Mesh Roll for the enclosure, and Rope for the trip cord.
Build on the ledges place traps on the east and west rooftop ledges.
Bait carefully noise and bright lights will scare the flock away for a while.
Cook everything raw pigeon must be cooked at the roof's open-air station on a Portable Gas Stove before you eat it.
Consider the Trapper class it builds traps faster, uses half the bait, and disturbs the flock less.

Exploring the building

Tips

In short Every floor has something worth finding, but infected spawns increase as you descend.

Bellwether Heights has 33 main floors, a ground lobby, a parking garage below that, and a rooftop. The elevator stops working on Day 3 when power cuts out, so all travel after that is on foot via stairwells.

Tips worth knowing

Floor 11 holds a medical clinic stocked with bandages and treatment tablets.
Floor 19's kitchen is worth visiting for food supplies and a good view of the street.
The Workshop on Floor 28 has a jammed door that must be pried open.
The ground lobby has the heaviest infected presence in the building.
The basement parking garage contains the generator and the last large water reserve, the cistern.
The rooftop has the extraction helicopter, the water tank, and the shelter site for the endgame.

Glossary

Cash: The in-game currency used to unlock classes, earned at 10 per day survived and 300 for a successful rescue.
Day 3 Cutoff: The moment on Day 3 when the building's water, power, and phone network shut off permanently.
Cistern: A large water reserve in the basement parking garage (B1) that remains accessible after the Day 3 cutoff.
Treatment Tablets: An item used to make untreated water from rain or the cistern safe to drink; each one has three uses.
Downed state: What happens when your health hits zero from an infected attack; a teammate can revive you to 60 percent health.
The Horde: A massive wave of infected that sweeps through the building on the evening of Day 15, marking the endgame.
Integrity: The durability value of a door or lock; doors start at 100, locks at 50, and reinforcement can push doors to 150.

Common questions

FAQ

What should I do before the water shuts off on Day 3?

Fill the bathtub, every bucket, the Jerry Can, and all your bottles using the working taps. A Funnel lets you move water from large containers into small bottles without spilling. Collect Treatment Tablets too, because rainwater and cistern water are not safe to drink without them.

Do I need a class to finish the game?

No. The Survivor class is free and can complete every objective in the game. Paid classes just make specific tasks faster, quieter, or cheaper on resources.

What do I do if infected surround me?

Head for the nearest stairwell rather than trying to fight. With up to three infected hitting you at once — dealing 16 or 28 damage per hit — you lose health very quickly in the open.

How do I get more food after the apartment supplies run out?

Build pigeon traps on the east and west ledges of the roof using Planks, a Mesh Roll, and Rope. Noise and bright lights will scare the flock away for a while. Any pigeon you catch must be cooked on a Portable Gas Stove before you eat it.

Can I save my progress and come back later?

Yes. Each player has one save file that can be opened, left, and deleted at any time — this was added in the October 31, 2026 patch.
