As far as I can tell, the two Tha'roon missions from the
War Wind demo v1.2 have been specifically made for demonstration purposes. The demo itself can be found here:

I'm not sure if the same applies to the other, earlier demo that has 4 missions (one per each race). At least, IIRC, the Obblinox demo seems to be from the full game. (The earlier demo appears to be more widely available, e.g. from
C|NET Downloads).
