Ahead of the next piece of Fallout 4 DLC, Far Harbor, Bethesda has kicked out a new beta patch.
The patch is now available on Steam and comes with more Survival Mode features and more stability and performance tweaks. To access the beta patch players need to opt-in by selecting settings, then betas, and selecting it from the drop-down menu.
Bethesda advise that anyone using third-party mod managers should back up saves and anything else that would likely be affected by testing the 1.5 beta.
Please Note: Survival difficulty characters are not backward compatible with the 1.4 version of Fallout 4. If you opt out of the Beta, do not use Survival character saved games.
