[Material Icons, Buttons & Host Migration] - 2026-10-01
Oct 1, 2026
Added
- Human NPCs: Human Army Guy, Human Army Guy (Friendly) and Human Scientist spawn from the NPC tab with the same behaviour as their Citizen versions
- Button tool: Place buttons and link them to anything that accepts an input, or bind them to a key
- Signal overlay: Pick inputs and outputs visually while wiring, and link components as well as objects
- Motor, Muscle and Winch tools return: Each now has its own model
- Revolver: A new weapon with its own view model
- Spawnlists: Add titled sections and dividers, re-order and remove items, change the icon size, and republish a list without re-entering its name and description
- Undo history: See your recent undos in the Utilities menu and undo any single entry
- Ignite and Extinguish: Set objects on fire or put them out from the context menu
- Follow me: Friendly combat NPCs can be told to follow you
- Pickup hints: On-screen prompts for things you can pick up
- View tilt, aim FOV and view model inertia: New options for how the camera and weapons feel
- Host migration: The game carries on when the host leaves instead of ending for everyone
Improved
- No more emojis: Every menu, tab, tool, tooltip, notice and editor icon now uses a Material icon instead, so icons look the same on every system
- YAS Box styling carried over: The new spawn menu, spawnlist, save, effects, tool info and context menu layouts keep the amber theme
- Spawn menu: Weapons have their own tab, entities are listed together, local and cloud content sit side by side with a verified badge, and the menu scrolls
- Toolgun removed from the spawn menu: Picking any tool already equips a toolgun for you
- Smaller NPC weapons: Combat NPCs hold smaller guns, shifted forward with the off hand following the grip, so they fit both Citizen and human bodies
- Clearer interaction prompt: The prompt for things you can use or pick up is a compact card below the crosshair instead of text over it
- Clearer Mounts tab: Installed games that are not enabled show an Enable button instead of an error, and the tab says when no games are installed
- Spawning cloud items gives feedback: You can see when something is still loading
- Easy Weld is now right click: Like in Garry's Mod, instead of a tick box
- Buttons can be welded to the world
- Physgun rotation: While rotating a held object, W and S move it forward and back and A and D spin it
- Noclip is snappier: Leaving it from a jump clears your upward speed
- Gentler landing and jump camera kick: Far less motion sickness
- Grenades chain: A grenade that takes damage explodes too, so shooting one sets off the rest
- Shotgun and sniper knockback tweaked
- Hud elements can be hidden: By cameras, free cam and add-ons
- Weapon switching can be blocked, and respawns can be cancelled by add-ons
- Console variables renamed: Most now start with `sandbox.` instead of `sb.`
Fixed
- Weapons dropped at the wrong size
- Ragdolls had no push from bullets
- Objects could not be rotated in gravity gun pull mode
- Snap grid stopped working at a distance from the world
- Wiring to a deleted object could break the tool
- Constraint and hydraulic attachments were tagged wrongly
- Pressing jump never played the jump animation on view models
- Muzzle flashes appeared in the wrong place
- SWB guns fired extra shots while the fire button was held: Single-shot weapons now fire once per click
[Smarter NPCs & Weapon Overhaul] — 2026-08-09
Aug 9, 2026
Added
- NPCs have relationships: Every NPC now knows who its allies and enemies are, and who it should run away from. Scientists fear monsters, rollermines hunt players, and hostile NPCs fight each other instead of only reacting to you
- NPCs notice what happens around them: Gunshots, deaths and other commotion carry to nearby NPCs, who will investigate the disturbance or panic
- New NPC behaviours: NPCs can follow you, investigate a noise, step aside when you walk into them, wander, and say goodbye when they leave
- New NPC voice lines: A full set for idling, following, being told to stay, getting scared, and getting stuck
- NPCs take turns speaking: They no longer talk over each other in a crowd
Improved
- Weapons rebuilt on the engine's weapon system: More consistent ammo, reloading, pickup and drop behaviour across every gun
- Dropped weapons keep their state: A gun you throw down keeps its ammo and settings when you pick it back up, instead of resetting
- Picking up a duplicate gun gives you its ammo: Rather than being refused outright
- Headshots on NPCs deal double damage: Matching how headshots already worked on players
- NPCs move at the right speed: They no longer get stuck sprinting or crawling after finishing what they were doing
- Rollermines are more dangerous: They now spot you from any direction, since a spinning ball has no real "front"
Fixed
- Right-clicking the M4A1 threw grenades: Secondary fire is aim-down-sights again, matching the other rifles
- You got credit for kills you didn't make: NPCs killing each other counted towards your score
- NPCs could still hurt you after dying
- Crash when an NPC had no weapon
- Spawned objects now land upright
- Weapon view models now show up in recordings
- Physgun and toolgun screens render correctly again
