Torchlight Infinite is being developed by XD Inc. and is the next installment in the Torchlight series. While no release date besides 2022 has been announced, there will be a closed beta for Torchlight Infinite on Jan. 18, 2022, for Android and iOS. This may leave some players wondering if there will be controller support.
The answer is no—Torchlight Iinfite does not have controller support, or at least not yet. Currently, there are only touchscreen controls which makes sense as the beta is only available on mobile. However, Torchlight Infinite will come to other platforms later, so it is likely that controller support will be implemented at some point, but possibly not for mobile.
Having more ways to play a game makes it more accessible for everyone. Whether it be touchscreen, controllers, or mouse and keyboard, all players have a preference of how they want to play, and this is no different for Torchlight Infinite.
Previous Torchlight games were released on console and offered controller support, so it would be only natural for Torchlight Infinite to have controller support. Perhaps in time, players will use a controller for Torchlight Infinite.
