This mod adds a "Campaign" menu item to the main menu enabling you to select a single player campaign and mission to play. Currently, the Ascension and Tutorial campaigns are listed, as well as the Postmortem campaign created by following WyvernNZ's SP Campaign tutorial, which I also included.
When starting HW2 a "CAMPAIGN" menu item should appear. Clicking on the button should take you to a menu where you can select a campaign to play, followed by another screen where you select the mission. The menus will also keep track of your progress in a campaign, just like the existing singleplayer and tutorial screens! That's as far as you will get, however, as I know of no way to actually trigger the beginning of the mission.
