Campaign is a ladder of rivals. You face them in turn, and each rival has missions
to complete.

Pick a difficulty (Easy, Medium, or Hard) before you start. Rivals you have beaten
are marked on the ladder, and the missions for the selected rival open in a sheet.

There are campaign achievements to unlock as you go.
