In Tormented Souls 2 New Game Plus, you can find 12 Nuclear Batteries hidden across the game. These are used on a special contraption located outside the Train Station entrance in Villa Hess. You can only fully use it after completing the Convent and collecting all batteries.
Below are all locations in order.
The Contraption Location
The machine that uses the batteries is outside the Train Station in Villa Hess. It becomes accessible after finishing the Convent area. Once all 12 batteries are inserted, you can claim a permanent unlockable device from the center.
