New small patch in publicbeta (v276)

Survivalist: Invisible Strain · published 15 Apr 2026, 17:50 UTC · build 22802494

All eventsPlayers around this dateRead on Steam

Hello, I've released another small update in the publicbeta branch. This contains some fixes and support for mods, and translator support. Also a slight tweak to combat; previously if you kept swinging your melee weapon at a zombie without being close enough to engage, they would back off, and you could in theory keep doing that forever - now after a few seconds of that they'll just attack no matter what.

  • Fix for crash in SIS Extended: Adaptive Combat

  • Fix for Out Of Sync errors in multiplayer if one player has previously run SIS Ageing without restarting the game since, and the other hasn't

  • Fixes for some errors in speech parameters, and added support for a female version of the word 'someone'.

  • Fix for exploit where you could keep swinging your melee weapon at a zombie forever without them attacking, as they waited for you to stop swinging

  • Possible fix for NPCs being slow to react to stuff on Huge maps using SIS Map Settings mod due to pathfinder queue getting backed up

  • Changed IsAnyoneInConversationWith condition to check all members of the community if you specify one (for modders)

  • Updated Japanese translation

Like the last patch I haven't updated the main branch or XBox as I want to give it a bit more time to settle.

What's this publicbeta thing?

v276 will be in the "publicbeta" branch on Steam for a while, before pushing it to the main game and to XBox. If you want to try the latest features as they come out (and help test them!) it's a good idea to start using this branch. But keep in mind:

  • Because it's the bleeding edge it could be less stable

  • If you want to be able to play online co-op with someone you'll need to be on the same version as them

  • If you go back from the "publicbeta" branch to the main branch you may not be able to load savegames created on "publicbeta".

To use publicbeta, just right-click on Survivalist: Invisible Strain in your Steam library and go to Properties, then Betas and in the drop-down select "publicbeta".

Game update19 Aug 2026Kicked v285 (the latest build, with pickpocketing) onto the main branch!Hello, just a note to say I've updated the main branch with the latest build in publicbeta, which means Pickpocketing is now fully released to everyone :) And I've updated the library page image with some new art from Ramiro Ra, who previously did the trading cards !

This is mainly to fix a crash when you try pickpocketing someone but your character is too moral or likes them too much to want to hurt them, which disables stuff like chokehold. But I didn't realise it was happening with pickpocketing, and the warning message caused a crash. There's also a fix for characters getting stuck in a loop finding wo…Survivalist: InvisibleGame update30 Jul 2026New small patch in publicbeta (v283)Hello, just a small publicbeta update with a fix for an occasional crash if something gets deleted while you are repairing it, and a fix for the SIS Move Props mod, which it seems got broken by a change I made back in 2025. Also a tweak to how the Dark Past and Loyalty quests select a landmark for a meeting place, they've often been using vehicles along the roads which wasn't the original inten…
