Call of Duty Zombies requires you to turn on the power in order to survive as the rounds progress and the enemies become more powerful. The Pack-a-Punch machine and Perk Machines are usually available, as well as new areas of the map. The round-based system in Call of Duty: Vanguard returns in Shi No Numa. Do you need to power up?
Call of Duty: Vanguard Zombies: Shi No Numa’s Samantha doll Easter egg
In Call of Duty: Vanguard Zombies’ Shi No Numa, how do you turn on the power?
No need to be concerned about Shi No Numa’s strength in Call of Duty: Vanguard. Unlike previous maps, this one does not have a power switch or other similar mechanism that prevents you from accessing certain parts of the area. Additionally, unlike Perk Machines, which require electricity to operate, the game’s perks can be obtained from water fountains.
In Shi No Numa, despite the absence of a power switch, you can still access the game’s electrical features. You can lure enemies into traps hidden in a variety of doorways, and the Wunderwaffe DG-2’s vacuum tubes must be charged in an unconventional manner.
We doubt that any future Vanguard Zombies maps will include the power switch. Even though it hasn’t been implemented yet, it wouldn’t be surprising if it did. Regardless of what game Treyarch brings Zombies to next, we can expect it to return.
