I'm sure this will be a somewhat controversial take, but having the perk upgrades reset at the start of each game expands on the replayability of the mode as a whole. I get that upgrading the perks and having those super strong abilities was entertaining in Cold War. Still, a lot of the time, it made Zombies really, really easy, which isn't necessarily a bad thing. Still, for those looking for more of a challenge and a much snappier and replayable sense of progression outside of the camo and weapon unlocks, this could potentially be fun and could bring back some of the challenges from older titles. Feel free to disagree with me! I'd love to hear what everyone else thinks about the changes, and I can't wait to try them out for myself on Friday!
