Scary seasonal gear is available to earn across all modes of the freshly released Black Ops 4 in celebration of Halloween, but that's just the start.
Zombie mode also now has the Halloween Calling, with exclusive rewards to earn through new challenges while mowing down the undead. Head over to the Zombie mode barracks to get full details.
Note that the event started and ends 7 days early for PS4 players. That means all platforms get the same amount of time to earn rewards, but PS4 players get first crack at it (and their time will end on October 27).
