LulzSec took down systems at the Escapist, Eve Online, Minecraft and League of Legends Tuesday during a three-hourlong distributed denial-of-service rampage that left gamers annoyed and the Lulz hackers crowing.

"Welcome to #TitanicTakeoverTuesday where everyone is laughing at crybabies getting Lulz Cannoned!" the hacking group said during

LulzSec emerged out of nowhere last month and immediately embarked on a series of high-profile hacking attacks, stealing data from Sony and game-maker Bethesda Softworks and compromising computers at the U.S. Senate and the Public Broadcasting Service, among others.

Unlike the better-known Anonymous hacking group, LulzSec doesn't appear to have any particular political motivation behind its attacks. The group takes its name from Lulz -- hacker speak for "laughs" -- and often appears to be hacking just for the fun of it.

Tuesday's attack started at the Escapist, an online magazine whose forums had swelled with angry comments after the Bethesda hack. "I want them caught and punished, a few years in jail for people like that would be hell," wrote Escapist forum member Psychicflash666 before the site was taken down.
