I am the top geographer in Minegarde. This is the record of my life's research. The Special Notes section of my work is information about the Fortress managed by the Guild.
The Fortress was created as the last line of defense against giant wyverns. The Fortress was established on high ground, giving it a better vantage point to keep a look out for these giant menaces. It also allows gunners to carry out sniping attacks on opponents below.
The Fortress also allows the firing of special, powerful shots from large siege weapons such as the Ballista and the Great Cannon. These weapons can be used when ammunition is transported to the Fortress.
Ballista S, normally marked with an X, can be used when standing in front of the Ballista. To use the Ballista, press the (box) button, then adjust the aiming by pressing left or right on the analog stick. Finally press the button to fire. If you press the (Right bumper) button while using the weapon, you can switch between scoped and standard views.
Cannon S is often held in reserve at camp, so it must be transported to the Fortress. While carrying Cannon S, pressing the button will set and fire the Great Cannon. Although it is a strong weapon, it does not have precision aiming, so hold off on using it until the time is right.
The ultimate weapon of last resort is the Dragonator. It can be activated by pressing the button at the control system located above the castle gate. It has limited range and requires a long duration of time as the weapon readies between uses. However, it makes up for these shortcomings with enormous power.
These weapons are hard to use, and their mastery takes significant time and energy; yet, they provide significant assistance in battle. Ultimately, if you envision yourself using these weapons, you must also envision yourself locked in a fierce battle with enormous monsters.
