You want to download this only if you want to create an add-on or if an add-on has this as dependency.
After installation, a new entry will appear in the main menu to switch the core.
This core is especially suited for add-ons which are not based in the dark age.
It uses from the default core:
- terrain graphics
- most of the macros
- all units
- all races
- all traits
- all abilities
- all specials
This allows to use your own units in a fresh environment.
IMPORTANT NOTICE: Switch back to the default core before joining multiplayer, unless you play with someone who also has this core in use. The multiplayer server does not know what core you use.
