I was originally going to remain as a lurker. I spend a good deal of time at the Freedom Force forums and am involved in modding for that game, so I did not want to get too involved in this one, although I am a longtime fan of the series.
This panicked discussion has compelled me to reply, however. You see, Freedom Force uses the same basic graphics system as Civ 4. Hundreds of new hero and object models have been made for that game. Thousands of skins have also been made.
There are three basic ways of creating a new unit graphic using this system.
1. Simply change the skin. It is amazing how different the same model or shape can look with a different skin. Since the skin itself is 2d, anyone with any artistic talent whatsoever can make skins.
2. Hex edit the model. There are hundreds of hex editors available for free. By hexing the model, you can remove parts of it, or change sizes or proportions. For instance, take the standard warrior and hex them to be more muscular, with longer arms, and reskin them, and you would have decent ape-man. I am sure I could get members of the Freedom Force community to help teach some of you hexing if necessary.
3. Make a whole new model. This is more complicated, and, at least for Freedom Force, does require more expensive software. Each new model, however, can in turn be hexed, yielding many more.
In addition, in some cases, keyframes from one mesh can be transfered to another allowing for more posibilites. So don't worry. Given time, a plethora of new things will be available. Expecially given how much larger the Civ community is compared to the FF one.
