Castles: The Northern Campaign

Installation

Uniquely for an expansion disk, the PC version of The Northern Campaign didn't so much expand Castles, as it literally replaced it! Installing the Northern Campaign replaces the original game, from the conquest of the Celtic lands, to the conquest of the Picts. So if you wanted to play the original Celtic five-castle campaign, you would have to reinstall Castles from scratch. The Amiga version instead used data from the original discs to create a new three-disk set onto blank floppies with the new levels and other features.
