In my mod "TFTD Vanilla Plus", I have used the fakeUnderwater tag as a "land" tag, this has worked very well for the most part. But upon further inspection, UFOs on land continue to use Depth and are not Airborne. other things such as this on globe and having to use "underwater" deployments can confuse people trying to develop land and underwater loadouts.
I was wondering if its possible to have the reverse option of fakeUnderwater, Like fakeSurface, that would denote all UFOs height to AIRBORNE, and would prevent certain xcom craft from engaging them and prevent Underwater only weapons from working on the "Surface:.
I am not sure how feasible it is to add both DEPTH and HEIGHT from both games, but that as well might add a some differentiation as well, requiring upgrades for higher altitudes and depths at the same time.
