As you spend more time in Vandorn Farm in Black Ops 7, you need to work your way around the map to solve puzzles and evade zombies. Your first job while you load into the map is to turn on the power, which might seem easy to say but extremely difficult to implement when zombies are crawling around the corner. This guide will explain how to turn on the power and also find the Pack-A-Punch machine in BO7 Zombies.
How to Turn on the Vandorn Farm Power in BO7 Zombies

You need to locate the Power Pump and shoot all the infestation off it to make it work again. Whether you load into the Survival or main map of Vandorn Farm, the objective will be the same. The Power Pump is located in the central area of the map. Upon inspecting it, you will spot several pulsating cysts covering it. Shoot down the cysts before they have a chance to regenerate. There is a meter on the right that keeps track of how fast you break the cysts off.
Once the meter has depleted, the Power Pump will be free and the objective will change. You now need to locate the power switch and turn it on to generate power to the farm. Head inside the large barn beside the power pump, an objective marker will lead you to the right one. It will cost 2000 Essence to access the locked door. After getting inside, head up the stairs to find the power switch and turn it on.
Pack-a-Punch and Perk-A-Cola Locations

On the same floor as the power switch, turn around to find the Pack-A-Punch machine. Next, there are two Der Wunderfizz Perk-A-Cola machines to find. You will spot one at Janus Tower Plaza, after taking the Jump Pad near the Power Generator. The second machine is inside the westernmost building, just straight from your spawn point. Head up to the second floor to find another Der Wunderfizz machine.
This isn’t the only secrets available in BO7 Zombies. You also get to claim a unique Ray Gun for free, work on your weapon loadouts, and also complete some Dark Ops challenges.
