​April 2026 Update     ​

New mountable gamesWith community effort and permission from the respective game developers, 2 new games are now available to be mounted in Garry’s Mod: Black Mesa and Military Conflict: Vietnam!https://store.steampowered.com/app/362890/Black_Mesa/https://store.steampowered.com/app/1012110/Military_Conflict_Vietnam/As with other mountable games, you will need to own them on Steam first, which will enable players to use maps and models from these games in Sandbox and other gamemodes.HUD ImprovementsSome default HUD elements received some polish – the weapon selector, damage indicators, health and ammo displays.The ammo HUD now correctly displays ammo for certain modded weapon types that use secondary clips, the default weapon selector can now display more slots and scroll weapon selection when there are too many weapons equipped to fit on the screen.The HUD now also scales better at 4K resolution, preventing certain elements such as Sandbox notifications and voice chat from overlapping the ammo HUD.New content & content fixesThe Combine APC is now a built-in vehicle, right in the spawnmenu, fully driveable by the player.There are also numerous bug fixes to existing models for various issues such as props becoming pitch black when resting on ground, fire effects not displaying correctly and spawning wrong gib models when broken.Network protocol changesThis update brings significant under-the-hood changes to the game’s networking, enabling faster network transfer speeds to reduce server join times, and removing a whole host of unnecessary networking done by various entities, hopefully reducing overall bandwidth usage, especially on initial player spawn.This update also switches many game systems to use double precision time, which should help servers to not need to restart or change maps as often and improve overall game feel after playing for a while on the same map.Smaller stuffAs usual this update also brings a huge amount of fixes and other smaller changes. Some optimizations to performance and memory usage as well.You can find the full change list for this update in our blog post:https://gmod.facepunch.com/news/april-2026-updateApril 30th HotfixDisable physics scaling optimizations – too unstableDisable static prop physics scaling – too unstableRemove “invalid sequence ack nr” check – gives false positivesFixed some ragdolls becoming pitch black when on ground post updatePrevent Entity:Spawn() on already spawned vehicles – This fixes a graceful exit which fixed a memory leakFixed APC gun effects not working for driver in multiplayerMade APC gun use airboat muzzleflash for player drivers so its not as blinding in first person viewFixed regression with Entity PhysicsCollide hooksDouble FIELD_ types support for internal variable entity Lua functionsFixed a crash with ragdolls when spawning them in teleport triggersMay 8th HotfixPotential speculative fixes for Peer 2 Peer connection issuesSlightly lowered default value of net_maxfragments (2800
