Sorry Don
Their based (or roughly based on) post-WCP:SO era ships. (nothing in this release was truely canon, although a couple demon (demon) and cobra (tembler) do resemble the real thing).
You don't need both model packs. They
should operate perfectly well without the other. If you do grab the first one, it would be wise to follow the Scooby-Update.rar instructions and replace the old additional.vp file. It fixes a small error and better balances the older ships with the newer ones and replaces most of the fs2 weapon sounds with WC's.
As for missions, there isn't much, a show-off mission (with just the ship) and a modified fs2 mission (usually the first mission, lion at the gate, or Exodus). I'm not a fredder, and I don't have that much time or knowledge of fred to put them all to good use.
HINT HINT Free Fredders PLEASE make use of these models. I'd like to see my work actually being used. HINT HINT
