Use this template to indicate that the current page represents a campaign. The syntax for this is:
{{Campaign | status = active or inactive | system = Game System Name | genre = Genre(s) separated, by commas | image = [[File: Image name.jpg]] | volume label = Volume (default) | book label = Book (default) | chapter label = Chapter (default) }}
There is no support for explicitly setting the campaign name -- the template will take the name of the page on which it is found. This limitation is by design.
