Currently there is an option for y axis to be inverted. However, there is no option for the x-axis, and unfortunately I am one of those people that need to use the dual invert option on the controllers. Without the dual inverted option, its almost impossible for me to use a controller effectively. Is this something that would be possible to implement on or before launch because I have a feeling I am not alone on this??

I whole heartily agree! I really like this game and want to play it very badly, however, I can't, because of the lack of inversion on the X axis.

OP seems not to tell us something

If you've ever wanted to see a useful visualization of thumbstick inversion options, play the game Rock of Ages and check out its control options menu. They have animations of little knights moving wooden joysticks around to demonstrate what the different invert options are like.

Long story short: the non invert options would require a geared joint if they were mechanical apparatuses while invert is simply a stick pointing directly out of the camera's backside.

Personally, I use a bizarre mix of different options depending on the type of camera. I invert Y for first person shooters with a controller, but do not invert with a mouse or when the camera is on a fixed rear axis (where you can't turn around or look in any direction beyond a maximum angle). To make things even more complicated, I like to invert X for third person camera controls, but not for third person aiming controls, though I think that has only come up in the Dead Rising franchise.

People's brains work differently, and it's a simple enough option for devs to implement (certainly simpler than explaining the reasoning), so let's let bygones be bygones.

One could easily get used to the different layout. The brain can rewire itself very fast
