Hi all, shoutout to @seanc, @BTAKaSpeR, and @Mudma for reporting an issue with controller compatibility with Windows 10. If you upgrade to Windows 10, you may find that the game behaves as though you are holding the joystick down in a single direction the entire time.

If you have this problem happen to you, we suggest downloading and installing the updated controller driver from this link: http://support.xbox.com/en-US/xbox-one/accessories/controller-pc-compatibility. We have found that this resolves the issue, and the controller will work normally.

Here are the steps to update the driver:
1) Open device manager and expand out Xbox Peripherals
2) Right-click Xbox Gaming Device and select "Update driver software"
3) Choose "Browse my computer for driver software"
4) Choose "Let me pick from a list of device drivers on my computer"
5) Choose Xbox Gaming Device Version 6.2.11059.0 [5/26/2014] and press Next.

Please let us know if you continue to have any issues after trying the new driver!
