Call Of Duty: Black Ops 6 players have already uncovered one of the game’s more disgusting easter eggs, which makes it rain zombies. Black Ops 6 launched on Friday (October 25) and players have already been putting a shift in. While multiplayer was available via early access beta tests, this weekend was the first time players could get involved with the single-player campaign and the return of round-based game-within-a-game Zombies.
