The Cold Storage is a warehouse located in the southern part of Driftveil City. True to its name, it’s absolutely frigid inside, with unhealthy layers of frozen water, which causes trainers to slide non-stop in one direction until they crash into something.
There are trainers here to fight if you so wish but we want to head to the left and pass through a fence. Follow the path as far south as possible and talk to the man standing in front of the building here. Once you’ve had a chinwag with the worker you and Cheren are free to head inside the building.
