The process of designing a vehicle is, well a bit too long. First,
you choose a hull design, and decide its size and configuration and armor.
Power supply comes next, then locomotion, communication, sensors and
electronics, weapons if you want, screens if you want, bridge if needed,
accommodations, and fuel. The system was designed in a way so that you can
use it to create vehicles, starships, or small crafts. The only thing I don't
really like is that it took a long time just to create a craft of any kind.
You can design crafts of any kind up to Tech level 21.
As for combat, well vehicle combat is covered in the personal combat
section, a vehicle is not very different from a person in combat except
it has more firepower/armor. The combat between two vehicles doesn't take
any longer than the combat between two people, thanks to the task system.
You can use civilan vehicles in the combat, too. It just can't fire back,
that's all. What kind of actions occur in combat? Well, you can fire,
you can evade, or intrupt someone else's turn if your turn go before his.
Image, tank A is fighting against B and C. A is aimming B ready to fire, but
C goes first. Thus C decides to perform a intrupt on A, (the form of intrupt
is up to you, you can fire or whatever. As long as it's something that A can't
ingnor. If you succed hitting A and push it aside. A lost it's turn, and B is
safe.) Using the combat system, I have done as many as 15 vehicles combat
without dragging it down...
