11:22, 13 Nov 2020

The day has finally arrived, and the world has fully embraced the Call of Duty: Black Ops Cold War Zombie apocalypse. After all, it's been eight whole years since we've had Zombie content, so it was bound to be the most exciting arrival of the game. 

However, if you're planning on securing your golden spot on the Zombies Leaderboard, you're probably going to want to make sure you level up your perks using Aetherium Crystals. Each perk, (and there's six altogether) can become permanently upgraded as you play through the mode - making it easier to obtain that elite status.
