All joule box upgrade locations in Mina the Hollower
Mina the Hollower features joule box upgrades scattered throughout the game that allow players to use their sidearm weapon more frequently. While these upgrades are typically hidden behind enemies and environmental obstacles, they provide meaningful progression for gameplay.
The upgrade system is straightforward: players begin with a maximum sidearm charge capacity of 20 joule. Each joule box discovered increases this capacity by 10 joule. Collecting all available upgrades raises the total sidearm charge capacity to 100, providing significantly more offensive flexibility and strategic options in combat.
In total, there are eight joule box upgrades available in Mina the Hollower, distributed across six different locations throughout the game world. Polygon has published a comprehensive guide detailing where to find every joule box upgrade, helping players maximize their sidearm resource management and combat capabilities.
