It has 80 range, 10,000 hitpoints, 500 attack and is 3 times more powerful against ships. The experience for destroying or building a fixed gun is 300. In the WarChiefs, during the Battle of Bunker Hill there are two Fixed Gun that Nathaniel Black and the Colonists can use against the British invaders.
