Hi, with this patch the controller support has been completely overhauled. This primarily leads to these changes:

• Improved compatibility with the Steam Input API. In other words, if your gamepad did not work previously, it hopefully does now
  
• Better names for gamepad buttons. E.g. "left shoulder" instead of "Button 4"
  
• The touchscreen support now also works on the Steam Deck
  

If your Gamepad doesn't work after this patch, there might be some incompatible settings left over within your Steam configuration. I cannot change these settings myself, because they are intended to override the settings I make as the developer. But you can change them quite easily. This post will show you how:

If there are any more problems, gamepad related or otherwise, please let me know with a forum post. And as always, if you want to make sure the new patch gets downloaded, simply restart Steam.
