Survival Log Shelter Defense: Doors, Windows, Traps & Hordes

Defense Starts Before the Horde

Survival Log includes tower-defense equipment such as sandbags, electric fences, and traps. A Radio warning can give advance notice of a zombie horde, which turns defense from a surprise into a preparation task.

Before the warning expires:

• repair every damaged door and window;
• stage repair materials beside the defense line;
• remove furniture that blocks access to openings or stairs;
• verify power for electrical defenses and critical appliances;
• prepare ready food, rest, and morale before survivors become busy;
• save a clear manual-action route for emergencies.

Door and Window Priorities

The most dangerous opening is the one already close to failure, not necessarily the front door. Inspect current durability and reinforce the weakest reachable point first. Keep materials centralized enough that you can redirect when pressure shifts.

Recent updates added an E-key repair shortcut after opening a door or window function menu. Use it to reduce interface time during a breach, but do not place traps or furniture where characters cannot reach the repair position.

Layer Traps Without Blocking Repairs

Traps should weaken or delay zombies before they reach the opening. They should not trap your own character away from the window that needs repair. Official patches changed pathfinding so zombies no longer avoid traps and fixed cases where traps blocked survivors near stairs.

Use three layers:

1. Approach layer: slow or damage the horde before contact.
2. Barrier layer: doors, windows, sandbags, or electric defenses absorb pressure.
3. Recovery layer: repair materials, power, food, and a clear path keep the barrier operating.

Exact trap damage and ideal spacing are patch-sensitive; use the current in-game descriptions.

Tense State Explained

Since the August 21 update, the protagonist and survivors at Home can enter Tense state when doors or windows are close to being breached during a horde. While Tense, they stop automatic eating, sleeping, and entertainment. Manual commands are not affected.

Tense clears after the threatened openings are repaired or the horde retreats. Repair the threatened barrier first, issue manual food or rest orders only when safe, and do not assume a survivor will automatically meet needs.

Power During a Horde

Power is part of defense if you rely on electric fences, lighting, refrigeration, or machinery. Decide what stays online before the attack. A fuel generator's auto-start state and batteries have received multiple fixes, so verify the current UI instead of relying on an old screenshot.

See the Power guide for generator and storage checks.

After the Horde

1. Repair all doors and windows, not only the final breach point.
2. Inspect traps and clear blocked routes.
3. Check fuel, batteries, and refrigerated food.
4. Feed and rest survivors whose automatic routines stopped.
5. Restock the repair kit for the next warning.

The Radio can broadcast a warning in advance. Use the warning period to repair and stage supplies.

Is this a real-world log cabin guide?

No. This page covers shelter defense in the Steam game Survival Log.
