Fortify is a real-time strategy castle defense game. You play as a lord in the northern region of Holgaria. Holgaria is under attack by creatures and as the first line of defense it’s your job to hold your fort!
You start at the Iron Age with only a few poorly trained sling shooters. As enemies attack you gain gold and can start advancing to Medieval Age and Imperial Age. The new ages bring new buildings, units and other defenses.
