|The Sub Battery is a mission item required to power the Submarine. It currently has no other functions or uses.|
Common Places Edit
The Sub Battery can spawn in a lot of different places, like the crew's rooms in the upper decks and generic rooms in the lower decks, but it can also be found in the Cargo Hold and the Engine Room. However, the easier way to find it is in the Power-Locked Rooms and barricaded rooms.
The sub battery is an easy item to find, so it's recommended to look for it in accessible rooms before opening a power-locked room, because after you might have a duplicate.
