The TLD Manual Save application is designed to give players a longer experience when playing survival modes. For instance, you’ve done the hard work – forged, hunted & crafted a bear coat – only to get killed by a wolf and have to restart a new game. So, if you die or make a huge mistake, you can reset the game to a previous backup & try again.
Download and uncompress the zip file. Move/Copy the folder to your desired location. Run TLD Manual Save.exe.
See Help Guide within the application for instructions on use.
