Survival Log Latest Update: v1.0.15690 Patch Notes & New Content

Current Version

This page tracks the live Steam build, not the older demo. Survival Log changed daily during launch week, so check the version before following a recipe or troubleshooting an appliance.

September 4 Update: v1.0.15690

The September 4 update is now the current tracked build. It affects endings, storage, recipes, and New Game Plus routing.

• Shield of the Street: adds a defensive support challenge ending. After Day 50, survivors at some trading posts can send distress messages while under zombie horde pressure. You can deploy Drones to lure the horde to your Home, defend against multiple increasingly large waves, and earn the challenge ending. All three protagonists can trigger it.
• Refrigerator weight limits removed: all refrigerator types no longer restrict stored food ingredients by weight. Power, freshness, and space planning still matter.
• Radish merged into Carrot: old-save Radishes are automatically converted to Carrots, and related recipes have been updated.
• New Game Plus Front Door change: in NG+ and later, Front Door Advanced Repair and Advanced Reinforcement can be used directly without completing the corresponding tasks.
• Related fixes: the update also includes achievement, handbook, mouse side button binding, interface stability, home pathing, and story presentation improvements.

Use the Endings guide, Crafting guide, and Recipes page with this version marker in mind.

September 2 Update: v1.0.15511

The September 2 note is especially relevant to recipe, crafting, and walkthrough pages because it touches the interface used to verify actions and the spoilage behavior players see after exploration.

• Operation Tips: issued commands now briefly show the operation icon, name, and target at the bottom of the screen. If route instructions feel ambiguous, use this display to confirm the command you actually queued.
• Cooking and crafting smoothness: the interface-lag optimization now also applies when opening cooking and crafting panels. Treat current-panel verification as the source of truth before copying old recipe or material counts.
• Exploration spoilage consistency: decay calculations for supplies in exploration instances now match Home, fixing cases where items spoiled immediately after being brought back.
• Update Log entry: the main sidebar now includes an Update Log button, with a red dot when a new version is available.
• Respawn presentation: respawn and rewind cutscenes received visual and music improvements, but the note does not publish new ending conditions.

Use the Recipes page, Cooking guide, and Crafting guide with this version marker in mind.

August 31 Update: v1.0.15369

The August 31 update added sporadic zombie harassment after the disaster and unified heating task requirements around having any working heating method installed at Home. It also renamed the Lying Flat endings for all three characters to Survival: Last One Standing.

That ending-name change affects guide wording, not a confirmed new ending route.

August 28 Update: Community, Food Sharing, and Large Ingredients

Late-August notes added several community-facing questions that older launch guides do not answer well.

• Food Sharing and neighbors: treat food sharing as a neighbor/community system first, then confirm whether the current objective wants a photo/share action or direct delivery. If the UI asks for a share action, do not spend the ingredient until the relationship step is complete.
• Giant Turkey and large ingredients: large ingredients may need cutting or processing before normal cooking and storage routines apply. Check the current recipe panel before assuming a large item behaves like a standard meat stack.
• Record Player behavior: recent notes mention automatic change behavior. If entertainment or morale scheduling seems stuck, verify the player, power state, available records, and the current patch before reporting a bug.

See the Community Discussion page for the short troubleshooting index.

August 27 Update: Crafting UI and Endless Mode

The August 27 changes are guide-sensitive because they affect how players read the crafting panel and long-run survival flow.

• Recheck recipe inputs in the live crafting UI before copying launch-week material counts.
• Use the updated Craft Again and material-source display to avoid queueing items from the wrong storage.
• Treat Endless Mode advice as patch-sensitive: horde cadence, long-run power planning, and food preservation can matter more than a one-week walkthrough route.

The Crafting guide and Gameplay Systems page now point players toward current-panel verification instead of fixed launch tables.

August 26 Update: Rotten Meat and Zombie Horde Rewards

The August 26 notes created a new practical loop around Rotten Meat and Zombie Horde preparation. Rotten Meat can matter as bait, but it is risky if placed without a repaired perimeter, trap path, and ready manual orders.

Use the Zombie Horde guide for the bait placement and defense checklist before intentionally attracting a horde.

August 23 Update: v1.0.14911

Heater and cold-wave preparation

The update adds a fuel-burning Heater. After a cold-wave warning, an event now prompts the player to prepare heating before temperatures fall. The official note confirms that the Heater is crafted from Sheet Metal and Wire. See the Cold Wave and Heater guide for a preparation checklist.

Electric Oven recipe

The Slow Roast and Fine Bake Planning Card now unlocks a post-disaster Electric Oven recipe. The confirmed materials are Sheet Metal, Electronic Components, and tempered glass. Before this patch, the oven was only available from a renovation company before the disaster.

Ration Press fragments

Ration fragments can now go back into the press. Four fragments can be compressed into one complete ration block without reducing their Satiety value. The update also fixes the press showing an active but unresponsive start button after a power outage and limits its material picker to the backpack and refrigerator.

Food freshness and outage fixes

The patch corrects several misleading or inconsistent freshness states:

• food outside a freezer no longer receives an incorrect Freezer label after Proper Storage;
• the Requires Fridge reminder displays again;
• refrigerator freshness bonuses persist through power loss, restoration, and manual switching;
• scavenged food shows the same expiration days in the backpack slot and item details.

If food still spoils unexpectedly, compare your version and storage state with the Food Spoilage guide.

August 22 Update: v1.0.14878

The August 22 build introduced the Ration Press. Examine the pile of papers in the Abandoned Hospital to unlock its crafting recipe. The press converts food into concentrated rations; the official note says nutrition is reduced while filling value is high, but it does not publish a universal conversion table.

It also added Tear Up This Round and Rewrite, a fourth rebirth option. It returns a new cycle to the first pre-disaster day, refunds Planning Points spent during that round, and does not consume a respawn chance. See the Rebirth and Planning Points guide.

Other changes included Deep Freezing display corrections, immediate cold-storage effects when cabinets move in or out, lower double-door refrigerator power use, and Perfect Crafting output adjustments.

August 21 Update: v1.0.14754

Two systems matter most for guides:

• Tense state: during a horde, survivors stop automatic eating, sleeping, and entertainment when doors or windows are close to failure. Manual orders still work.
• Warehouse Manager journey: two new events unlock recipes for solar panels, energy storage equipment, and heating equipment.

The same build changed trap pathfinding and removed the trading prerequisite from Drone Supply Drop when someone in the supply network is alive.

Patch-Sensitive Facts to Recheck

Furniture power draw, freshness multipliers, recipe output, event timing, and crafting quantities can change. This wiki treats the official update feed as the source for patch changes and labels anything not stated there as to be confirmed in the current build.
