How to add Torchlight II to Steam
Torchlight II keys purchased from Runic Games -- or one of our partners, such as Perfect World or Daedalic -- before February 2, 2015 may be added to Steam. To do so:
- From Steam, navigate to the Games menu.
- Choose Activate a Product on Steam...
- Follow the prompts.
At this point, Torchlight II will be activated and should automatically begin downloading. Once this is complete, you can run it from your Steam library by clicking Play, or by double-clicking it from the list.
