The Fortress is a large and powerful giant unit that uses its massive shoulder-mounted cannons to inflict single-target damage on grounded targets from a long distance. Unlike the similarly-ranged Marksman, whose upgrades mainly focus on increasing its combat ability, the Fortress' vast array of upgrades allow it to fulfill a variety of roles. Upgrades like Barrier and Armor Enhancement allow the Fortress to sponge heavy damage from incoming attacks and draw area-of-effect attacks away from your more fragile units, while upgrades such as Range Enhancement and Doubleshot can turn the Fortress into a weapons platform able to decimate enemy units from afar. It can even gain the ability to attack air units using Anti-Air Barrage, though its 10-second cooldown between attacks means you'll likely still need other anti-air options to address airborne threats.

The Fortress also receives a unique upgrade in Fang Summoning, which allows it to periodically spawn a group of Fangs. Fangs already have good synergy with the Fortress by dealing damage to air units the Fortress can't touch, while also drawing fire from units like Marksmen or Phoenixes that would otherwise threaten the Fortress. If you've upgraded your Fangs into powerful lategame units, this upgrade allows you to get further return on your investment by producing more fangs mid-combat.
