FEM – Full model export.

There would be something to continue with; everything possible was extracted from the alpha (you could create a mod like an alpha Haven faction, and that would be it). In the closed beta, which we have, there isn't much content either; besides the textures, there isn't much to extract. What exists, and as I understand it, this isn't the very first version of the closed beta, at least because screenshots for the Isabel campaign were made based on it.

P.S. I found a map in the alpha version that shows all the objects that exist and that were planned, but I doubt that it makes sense to use any of them.
