Broudo: I'm playing via keyboard and mouse. It's working. I managed to survive for almost four minutes. Game controller would be easier. Is it possible to enable the game controller, please?
It works with any Xinput pad.
The stick sensitivity isn't great though. I had a hard time lining up headshots and moving about felt coarse and inaccurate. It's not like the sensitivity curve you see in many shooters.
So far the best experience I've had is with KB and a thumb trackball mouse. The flicking motions required and autoshooting lend itself well to this config. Much less tiring than a regular mouse.
