Ubersprengen

"Newly unlocked, the machine sits ready to receive weapons. It seems to upgrade weapons with power and unique traits. Upgraded weapons can also have their ammo restocked here or at their corresponding Weapon Locker."

Ubersprengen is a utility found in The Final Reich, as well as in a small easter egg within Gröesten Haus. It is essentially the Pack-a-Punch Machine from previous Zombies installments. Unlike its predecessors however, the Ubersprengen can resupply ammo to any weapon, including weapons that aren't normally found from Weapon Lockers. This can be done for 4,000 Jolts once the weapon the player wishes to restock is upgraded.
