OK, this was interesting: I was going throught the ini files for the campaign maps, and found reference to a unit called "ChinaVehiclePropagandaBlimp".
I could think of two reasons why it's not in the game:
1) The demoralize code was removed/disabled, and the blimp would've used it?
2) EAP felt the Overlord with a Propaganda addon should suffice.
Anybody else got a theory, or even perhaps a link where we could get this model?
In reply to Tebrey - I'd love to, but I'm not a modeler, I do INI. Oh, well, I'll just ask someone like Sleipnir or Deezire if they could perhaps come up with something. DZ is probably re-enabling the demoralize code, so he might know.
Im not doing anything with the demoralize code as it doesnt work. The Propaganda Blimp never even got coded/modelled, it was a very early idea that got dropped almost as soon as it was conceived - too RA2-ish.
It appears in the map.ini files because it remained on the object list that the developers used for reference. Theres other objects in the map.ini files too that never made the grade either.
