Call of Duty's Festive Fervor event is live in Vanguard and Warzone, bringing elves and Krampus as special events to terrorize players. Unfortunately, Krampus is indeed everywhere in Vanguard, which includes the private matches being used by professional esports players.

Krampus pops up in Vanguard matches as a random event, and he is said to be targeting whoever has the least impressive objective score. The creature will eliminate his victim with a finishing move if the targeted player can't kill him fast enough. Players are also reporting Krampus to be a bullet sponge, making it really hard to dump enough bullets into him before he attacks. This can be frustrating for even the average player, but none of this is ideal if you're a professional player practicing for an event.

Several clips like the one below have been shared by esports players, showing Krampus being an absolute nuisance in private matches.
