Avert your eyes.

On Sunday night hackers stormed major cities in the online adventure game World of Warcraft and killed innocent avatars everywhere.

Forbes quoted a player:

“It was really weird. I was [away from keyboard] for like one minute, and when I came back I was dead and so were everyone else. Really creepy. I wonder what happened.”

TG Daily reports:

"The entire populations of Stormwind, Orgrimmar, Tarren Mill, Ragnaros, Draenor and Twisting Nether - both avatiars and NPCs - were wiped out completely for about four hours. What appears to have happened is that one or more Level 1 characters was able to execute a script that invoked a spell called Aura of God to kill everyone around."

A Youtube video uploaded Sunday said, "one of the hackers ... went across different servers with a level 1 char, flying around and insta-killing everyone. Happened over several hours, filling Stormwind with death. Initial reports of the Rapture were found to be incorrect."

Blizzard HQ issued a statement:

“We apologize for the inconvenience some of you experienced as a result of this and appreciate your understanding.”

It appears no permanent damage was caused, and players are now back to slaying dragons.

Here's video of the carnage:
