This is a 100% Walkthrough with commentary to collect all items and collectibles and get the True Ending of the game. Feel free to let me know if I missed anything. (I am aware I didn’t use the rare herbs with the medic character, however, it only creates some med kits and I found that to be an unnecessary death to show that off.)
I will also update the guide or create a new one if/when achievements are added.
