No. The hardcore wipe only made changes to the PVP mode. SPT 4.0 is using EFT version 0.16.9.0.40087 which came before the softcore wipe changes were added to PVE.
You can easily recreate either using mods.
4.0 be updated to include the latest EFT patches?No. EFT patches made after the release of SPT 4.0 will only be available in SPT 4.1.
4.0 than in 3.11?Short answer: A bit.
Long answer: BSG optimised culling on several maps, and alongside other changes, did somewhat improve performance between EFT 0.16.1.3.35392 and 0.16.9.0.40087. It’s most noticeable if your SPT is GPU limited and will vary. The Performance Tuning guide is still relevant even on 4.0.
3.11?If the 3.11 profile was un-modded, yes. Otherwise A new profile will be required. None of your 3.11 mods are compatible.
See the guide on Updating SPT for more details.
3.11, can I re-download it?Yes. SPT 3.11 is in Long Term Distribution. However, you will need to manually install it and we offer no support for it.
See this guide for instructions.
4.0?Nobody knows when certain mods are going to update, not even the authors themselves. Do not pester mod authors about updates to their mods.
4.0.0 work on future versions of 4.0?It should. Mods known to be incompatible with be stated in the Mod compatibility section of SPT’s Release page.
Mods discovered to not work will also be noted in <#1424144572858110052>.
For an explanation of how SPT versions work and how to update your SPT, read through the Updating SPT page.
Base SPT uses EFT’s PVE spawning system, which does not check the distance to you or other bots. Use a bot spawning mod to address it.
The Infected Halloween event is enabled by default in SPT 4.0. It runs from the 28th of October to the 9th of November. You can see the maps infection level on the pre-raid screen.
The zombies are from a 2024 event, which means it has some issues in the current version of the game:
Vanilla Scavs in Home > General > Vanilla Bot Behaviour Settings will prevent the slide-crouch loop, but will not fix zombies’ melee.SPT 4.0.3 brings many fixes for the event. You should update your SPT.
If you want to disable just zombies, enable Raid Settings > Events > Disable zombies in SVM. To disable Halloween completely, enable Raid Settings > Events > Disable ongoing events or use Politely Remove Events.
Start removing mods one at a time, or if you have a lot of mods, follow the 50/50 Method.
If none of that helps, then it’s time to create a support ticket. Join our Discord Server and read through the #support-guidelines for instructions.
We currently host two version of SPT: version 4.0, using EFT version 0.16.9.0.40087, released 2 October 2025 and a Long Term Distribution version of SPT: version 3.11.4 released 1 September 2025, using EFT version 0.16.1.3.35392 released 5 March 2025.
While you can install version 4.0 using the SPT Installer, installing 3.11.4 can only be done manually by following this guide. We do not offer support for 3.11.4.
We do not host older versions of SPT because each SPT version is specifically designed to work with a particular version of EFT. Since EFT is a live service game that receives frequent updates, every SPT version requires a dedicated patcher to downgrade your local EFT installation to the compatible version. Maintaining multiple older SPT versions would necessitate actively maintaining multiple downgrade patchers, which includes updating these patchers after each and every EFT update. Our team simply does not have the time to dedicate to this level of ongoing maintenance.
