# The Watchtower **probably the most important building on your farm after the headquarters.** This is where you will find your warriors on an automatic machine gun that can spray your enemies and stop their attack.

It is equally important to upgrade the watchtower from attackers and defend your farm as it is to upgrade your army and advance your attack. **The farm will start with only one watch tower,** and players can build another one immediately if they have enough FW coins. The player can build more watch towers as the farm progresses in levels. To upgrade the existing watchtower player will need to mint an upgraded NFT and [claim the new and improved automatic machine guns](/chapter-5-the-farm-wars-game-mechanics/upgrading-the-farm/upgrading-weapons.md) to defend your farm. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
