Sons of the Forest Patch 09 – New Cannibal Type, Fixes & Improvements

Following a large update last month, the game’s most recent patch mostly focuses on bug fixes and some gameplay improvements. Specifically, Endnight wanted to polish up performance to improve stability of larger player bases. Yet, there is still a little bit of new content to be excited about, such as the ability to place held Radios, a new radio alarm trap, a new large cannibal type, and a returning creature added for the endgame.

It’s also worth noting that, with all of the fixes now out of the way, it’s not unlikely we will see a more substantial content update soon.

Feel free to peruse a few other additions and a long list of bug fixes in the official notes below.
