30 Floors Up Survival Guides

Last updated: 2026-11-02

Survival in 30 Floors Up is a supply loop: find food and water, seal the apartment, and keep the hallways quiet so zombies never learn where you are. These guides cover the opening session, the individual supplies and defences behind that loop, and how to keep it running alone or in a group.

Articles and Guides

Beginner Guide: Your First Session

Plan your first session: scavenge food and water, barricade the apartment, move quietly, then pick solo or co-op.

Where to Scavenge Food and Water

Run supply trips through the building safely: what to loot first, what to watch for, and why supplies come first.

Apartment Defense: Keeping Zombies Out

Hold your apartment with a barricade, quiet hallways and stocked supplies, so zombies stay outside your door.

What the Zombies Do and How to Avoid Them

Learn how hallway zombies react to noise, what a barricade stops, and how supplies keep a supply run from turning fatal.

The 100-Day Goal and What It Asks

Understand the 100-day survival goal and the daily habits behind it: food, water, barricades and quiet hallway movement.

How Food Works and How to Eat It

See how scavenged food, canned goods, spoons and hunger fit together, and what a daily eating routine looks like.

Storing Water and Why It Matters

Scavenge water, keep the supply in your apartment, and learn why staying stocked keeps you able to run.

What Barricading Your Apartment Does

See what an apartment barricade actually keeps out, how it fits the survival loop, and when to re-check it.

Moving Quietly Past Hallway Zombies

Cut noise by not running, then keep that habit through scavenging, water storage and barricading so zombies stay away.

Rooftop Shelter: What It Is For

Build a rooftop shelter as a place to rest and plan, and see how it fits alongside your apartment barricade.

Getting Through Hallway Zombies Safely

Cross zombie-filled hallways by moving quietly instead of running, and treat your barricaded apartment as the safe return point.

Solo Survival: What Matters Most

Play alone with the same loop: scavenge, store water, barricade, and stay quiet without a teammate covering the gaps.

Eating Canned Food and What Opens It

Canned food keeps you alive and normally needs a can opener; the Spoon game pass adds a spoon you can eat with.
