The keychains are actually sick. Opening a new door every day and seeing which Zombies item I got made this way more fun than a normal advent calendar. Definitely keeping these on my setup

Every door has a different Zombies-themed collectible keychain inside. The little perk machines and other items have way more detail than I expected. Such a cool idea for COD fans

Wasn't expecting the mini keychains to have this much detail. Getting a different collectible each day made the countdown addicting. The whole calendar looks sick sitting next to my gaming setup. 10/10.
