A large group of Word War II Online players had appeared during Second Life's beta and sequestered themselves behind the Jessie Wall in order to battle amongst each other. During the Iraq war, some of them began plastering the wall with pro-war posters. Pacifists quickly countered by covering them with anti-war signs. The vitriol escalated into violence.
Still, the World War II Online gamers' penchant for disruptive behavior aside, many at Linden Lab loved their invasion.
"They all came in to check us out. They took over ... about 16 acres and said, 'You come in here, we'll kill you,'" Rosedale said. "This one guy who built and sold guns had this little gun shop in the hinterlands.... And the WWII Onliners got on their little island, which happened to be next to this guy's gun shop. In one week, he made $100,000 (in game currency) selling guns to these guys. That was just the coolest thing."
