LibGDX top down oblique camera view

The time has come where I need to ask how to do this. I experimented for about 5 hours last night trying to get this to work correctly. I was trying to use (OrthographicCamera) camera.rotate() and camera.rotateAround() and I just can’t seem to get the camera to rotate how I want it to. Although it does rotate every other which way I don’t want it to. Currently it is just top down, and I want to tilt it backwards. So basically two questions. 1: Are these the correct methods to be using in order to achieve top down oblique view? Can this be achieved by a 2d camera or should I switch it to 3d? And when I tilt it backwards, I’m tilting along the Y axis, correct? Sorry I’m such a noob and can’t get this to work.
