On Star Trek TOS, you will see a complete mod from the Kirk era made with the stuff from Star Fleet Command TOS mod and many more new things. Thanks to all these creators, this mod will be finished very fast and with great quality. At a first place the mod will add only space combat but for a non too far future, I wait add ground units.
While I finish and fix all the missing things which I discovered, I have added a new unit, it will be the Longbow refit. I made it with parts from the TOS Longbow and the TMP Enterprise.
All sides will have a few starships which they can be upgraded as the Longbow. Other features will be the different stations which you can build or sell for replace by others.
I have been tring to code upgrades like this for a few units but I can't figure out how to make it work properly in GC
Some people use xml code and it is long, very long but I use small piece of xml and a small lua code made by TAU at a first moment which I have adapted for multiple uses.
