The Gun Fort, a formidable stronghold within the Sunken Valley, serves as a significant obstacle for players due to its heavily fortified nature and the specialized weaponry of its defenders. This area is characterized by its numerous cannons and rifle-wielding enemies, whose ranged attacks can inflict substantial damage from a distance. Players must utilize cover effectively, moving from one piece of rubble to another while carefully observing enemy patrol patterns. The fort's layout features multiple levels and interconnected pathways, often requiring the use of the Grappling Hook to ascend to higher positions or flank enemy encampments. The sheer volume of projectiles fired by the fort's defenders can create a chaotic battlefield, making it difficult to find openings for attack. Mastering the deflect mechanic is crucial, as parrying cannonballs and rifle shots can create opportunities for counter-attacks. also be aware of the explosive barrels scattered throughout the fort, which can be detonated to damage groups of enemies.
Progression through the Gun Fort involves a strategic approach to overcoming its defenses. Players will encounter elite soldiers armed with firearms and powerful melee weapons, often working in conjunction with the fort's artillery. The presence of the Flame Vent prosthetic tool can be highly effective in clearing out groups of enemies or creating distractions. Looting the Gun Fort can yield valuable items such as Divine Confetti, which is essential for dealing damage to certain spectral enemies, and various Spirit Emblems. The fort also contains hidden passages and secret areas that may lead to valuable rewards or shortcuts.

Rushing into the open will likely result in being overwhelmed by gunfire and cannon fire. The ultimate goal is to disable the fort's defenses and find a way to proceed further into the Sunken Valley, a task that demands patience, tactical thinking, and a mastery of Sekiro's combat abilities.
