I did some research on the issue of not being able to use the controller. I found that if the Steam controller setting was set to [Enable Steam Input], the controller would not respond. RUMBLE BLAZING is compatible with XINPUT type controllers. If it doesn't work with a XINPUT controller, try the following. Right-click [RUMBLE BLAZING] from the Steam game list and select properties. Please select [Disable Steam Input] from the [RUMBLE BLAZING Override] setting in the properties controller and try launching the game.
