Sirocco is a planet that is, or at least was settled. A significant portion of its surface, if not all of it, is covered in barren desert.
The planet serves as a multiplayer map in StarCraft: Brood War. It supports up to six players.
The planet is likely named after the Sirocco wind, a Mediterranean wind that comes from the Sahara and reaches hurricane speeds in North Africa and Europe.
