Game and Unit development

Mod development

Mods, next to Maps, is the content used in Spring.
A mod is simply a combined file containing a small structure of files and directories holding all the data required.

Mod Development wiki is a starting page, linking to very useful information on the files included in a mod, their hierarchy and more.

Almost the entire mod developing is the creation of units. Which isn't an easy job.
Information about the creation of units are everywere, but not combined.
