Torchlight II received a default branch update on Steam: the Steam login replaces the TapTap.io account for online multiplayer.
Torchlight II is an action RPG with randomized levels, loot and enemies, plus online and LAN co-op. It runs natively on Linux and is currently on sale for €3.79 (-80%, regularly €18.99) in the Steam Store. The deal runs until November 16.
Dear players, Today, we updated the default branch on Steam to remove the TapTap.io account login for online multiplayer and replace it with Steam account login.
After this update, you no longer need to register for or log in with a separate TapTap.io account to access online multiplayer. The game will automatically authenticate through your current Steam account and load the corresponding Steam friends list.
Please note that your in-game friends list will change with the login account. In-game friends previously added through TapTap.io will not automatically sync to your Steam friends list.
This update only changes the account authentication method for online multiplayer. It does not change any other game content or multiplayer services. Single-player mode and local saves are unaffected.
We will also continue working on fixes and improvements to address other issues reported since the previous update.
If you encounter bugs, save issues, or compatibility problems in the new version, please share your feedback through our official community. Where possible, include your game version, operating system, and details of what happened to help us investigate. Discord: https://discord.gg/ahCyDEndtk
If you encounter multiplayer issues, please follow the diagnostic and reporting instructions in our previous announcement: Thank you for your understanding and support!
