It's too funny that you were the one to respond. I just seen your post this morning about The Forest when my wife sent it to me. It was well done!

Tree houses are amazing because the cannibals don't seem to try climbing up. They make for an incredible place to go hid at night.

I've not found any use for the SOS either to be honest. I had a ton of stone building up so I just threw one on an exposed area in case it could benefit me. I have a feeling it's more or less cosmetic.

I've not really made it past the first 5 days or so. The game is still extremely new to me. I only found out about the treehouse because someone told @katikat and I while we were streaming it the other day.

Edit: Thanks for coming by the video! I just sent you an HBI share :)
