Sons of the Forest Patch 13 – Cave Changes, Tarp Walls, and New Items

Endnight Games has been on a roll with their latest patches! The last patch, Patch 12, had some solid additions like a new cave, crafting component, and item. They must be hard at work because this newer patch looks to be just as good, if not better.

It would seem they have not only made major changes to two of the caves (The Gold Armor Cave / The Rope Gun Cave), but they also added two new mystery items. For the builders out there, they also gave us three new findable blueprints for construction (one of them a new trap), and the ability to make walls with tarps.

Furthermore, they added a whole mess of improvements and fixes. Normally, we would give you a summarized list of the patch, but there are so many notable changes in each section that we recommend skimming the entire thing yourself.

Sons of the Forest Patch 13 Notes

Hey everyone,

This patch re-works Cave D (the gold armor/rifle cave) adding a bunch of cool additions and some big surprises. We also added a new extension to cave B (the rope gun cave) two new ??? items, and 3 new findable blueprints.

Additionally we added a new skinned enemy type who is very aggressive, gave twins the ability to burst out through the ground, and lots more. For the full list check below
