3.25.10.0 Update Notes

Posted on December 4th, 2025 11:50 AM EST
Engine Update

We've upgraded to Unity 2022 LTS, primarily for improved stability. Related updates include:

  • New SMAA anti-aliasing option as an alternative to TAA or FXAA.

  • Major upgrade to the pathfinding library used by zombies (A* Pathfinding Project). This fixes a variety of server-side pathfinding bugs and may improve performance.

  • Taking advantage of some new performance optimizations.

We'll be keeping a close eye on bug reports, as this kind of update has many side-effects.

Full Changelog

Quality of Life
  • Vanilla sentries immediately react to gunshots and melee hits. (They turn to where you attacked them from.)

  • Searching workstation capability names in crafting menu filters blueprints producing items with that capability. (For example, "Heat Source" will find Campfires.)

  • Raised detonator max selected charges from 8 to 16. Let the pyrotechnics commence!

  • Reworked water transition into sky to avoid revealing topography of underwater terrain.

Character Customization
  • Added beard color option separate from hair color. NPCs and cosmetics can use this, too.

  • Many cosmetics covering the lower face use your preferred beard color.

  • Cosmetics take priority over NVGs in singleplayer and PvE where they don't affect balance. (Ignoring the Priority_Over_Cosmetic setting.)

Servers
  • LDM dependency-handling patch for 2022 LTS. (Thanks Senior-S, DanielWillett, and Paradox304!)

  • Revised server backup naming to improve terminal tab completion: rather than appending "-backup" to the file name, a tilde '~' is appended to the extension. For example, auto-completing "Conf" to "Config.txt" as the more common operation.

  • Fixed server not writing "-backup" files after 3.25.8.0. (Thanks CatzTimes!)

  • Fixed not re-serializing server Config.json when -UseLegacyJsonGameplayConfig is enabled. (Thanks CatzTimes!)

Audio

3.25.8.0 experimented with enabling the doppler effect, which was previously disabled project-wide. Many audio sources weren't configured with this in mind, so it was reverted in 3.25.8.1. This update re-enables it, and disables per-audio-source by default during load for backwards compatibility.

  • Added "Enable Doppler Effect" component to bypass disabling doppler effect.

  • Enabled doppler effect on vanilla emergency vehicle sirens.

Localization
  • Objects with dialogue (like interactable computers) can show a different display name with Dialogue_Name localization key.

  • NPC "hints" in multiplayer use client's language if Keep_Localization_Loaded is enabled.

  • Updated a few cases where translation fallback to default was unsupported. (Such as item names.)

  • Fixed Covert achievement description spelling mistake. (Thanks Zeenotzed5!)

  • Allow sending single-character chat messages because they can be meaningful in other languages. (Thanks CatzTimes!)

Level Editing
  • Added level underwater fog effect density override. Useful for maps featuring a longer underwater view distance.

  • Levels can adjust default config per-difficulty (easy/normal/hard).

  • Added option for per-navmesh vs per-zombie-table difficulty asset prioritization.

  • Resources can set Legacy_Rotation_and_Scale false to use newer surface alignment options. For example, we're using this to place mineable clay on cave ceilings in a future update.

  • Per-object savedata is more resilient to removing/moving objects in the level editor. (Thanks clue!)

  • Fixed missing level Has_Atmosphere option turning off stars. (Thanks Strekazyabrua!)

  • Fixed editing devkit node properties not marking the level dirty. (Thanks LocoCZ!)

NPC Modding
  • Added effect OnlyRelevantToInstigator and event InstigatorOnly options. For example, to limit showing a UI popup only to the player who triggered an interaction.

  • Added "Overlap" volume type and condition. This can be used to test whether an area has a certain number of players in it.

  • Added ability to respawn and kill zombies from NPC logic.

  • Added "/RunRewardList" command for testing NPC reward list assets.

Unity Mod Hooks
  • Added Vehicle Gearshift Event Hook for gear number changes.

  • Added Vehicle Health Event Hook for testing current health.

  • Vehicle Event Hook now exposes events for all replicated properties.

  • Added "Damage Collision" component for damaging (rather than killing) on contact.

Miscellaneous Modding
  • Added support for ammo to override rocket/grenade launcher projectile.

  • Added support for low-quality lockpicks that fail to unlock the vehicle.

  • Explosive magazines can disable impact effects. (Useful for multi-pellet explosive shotguns.)

  • Gun items with auto description off can opt-in to listing attachments.

  • Added storage Default_Contained_Items list.

  • Added vehicle options for keeping engine/wheel RPM more closely in sync. (Experimental)

  • Added sentry options to bypass PvE, react to attacks, and adjust sweep timing.

  • Added barricade incoming ranged damage falloff multipliers.

  • Improved context for master bundle reference error messages.

Miscellaneous Fixes
  • Moved Vanguard vest mythical effect forward so it's less obstructed. (Thanks ZHR!)

  • Regression parsing (x, y) and (x, y, z) vectors from dat. (Thanks Sultan!)

  • Crash reloading gun with more than 255 magazines. (Thanks CatzTimes!)

  • IsOverride key missing from spawns editor round-trip. (Thanks WW-TC!)

  • Inconsistency playing inventory audio when quick-moving item to/from storage. (Thanks WW-TC!)

  • Inconsistent bounds checks placing barricades on vehicles in multiplayer. (Thanks Eismeister!)

  • Fix rubble respawn all sections not working properly. (Thanks Xylemo!)

  • Oversized invite icon in lobbies menu. (Thanks Jdance!)

  • Misaligned mythical effects on Pool Cue. (Thanks TrueNinjafrog and dr4c0ottv!)

  • Animals without physics material default to vanilla flesh material.

  • Gun Delete_Empty_Magazines behaving differently for non-projectile weapons.

  • Cinematic mode respects FarClipDistance command-line override.

  • Simplify instigator tracking for nested rockets/grenades.

  • Unable to interact with destructible object fuel/water tanks.

  • Error writing singleplayer config on first load of a fresh install.

Special thanks to all of the players who tried out this update on the preview branch and helped report bugs!
