I cannot work out for the life of me how to do this…
The player is allowed to angle the camera, however, i want the camera to exist on a fixed Y axis, as such only the X & Z parts of the vector will change and Y will remain constant.

My only issue is is that if i use transform.forward it will always change the Y axis if the camera is pitched, and if i use transform.forward and set the end results y value to the fixed level i want, the speed of the camera is directly affected by the pitch and i want it to be completely independant, constant Y constant movement speed camera, how would i do this? Can i not use transform.forward?

Easily: If you’re using this to move the camera in a forward direction along the y-axis,

// Get the forward vector along a constrained Y-Space
Vector3 ConstrainedForward(Transform focus)
{
	// Get the natural forward transition
	Vector3 naturalForward = focus.forward;
	// Nullify its y-component
	naturalForward.y = 0;
	// Normalize xz-plane and align it with the chosen y-axis
	Vector3 fixedForward = naturalForward.normalized;

	// This gives us a vector whose xz-planar speed is normalized
	// while preserving the fixed Y component
	return fixedForward;
}
