Being a first-person tactical shooter set in an MMO environment, Gray Zone Warfare's controller support would be very useful, not only for those who prefer using controllers in FPS games, but also for its accessibility.
How to play Gray Zone Warfare with any controller (gamepad)
Not all FPS games for PC, especially those still in early access, offer controller support, but some do.
Unfortunately, Gray Zone Warfare does not currently offer controller support, either fully or partially. This FPS is only available on PC via Steam, so you cannot play it on console platforms such as Xbox or PlayStation to enjoy with a controller.
Since Gray Zone Warfare is in early access, the hope is that controller support will be added during this time or when the game fully launches. However, Mad Finger Games has already stated on the Gray Zone Warfare Steam page that there are plans for a full release, but it will not include controller support.
