Two things strike me about this post.
1. Just yesterday I was jonsing to fly some Tomcat missions, and so I did.
2. While setting up the mission and loading I was remembering that F-14 Fleet Defender had a UFO mission ( "something was sighted, go check it out," but that was near Cuba).
And then I was wondering how to create such a mission, or more better, an Easter Egg, of a "something" half buried in the "somewhere" in a map. In DBS there could be a crashed Hydra bomber, Fortress of Solitude, Preditor or Alien ship....something. I am not a terrain or model builder, but that kind of stuff would be neato.
BTW, F-14:FD is on Steam for $6.99 USD (I paid $45 in 1994).
On topic, I have no idea how to fix the tile set.
