Since everyone is mostly playing nice in the DZ now, and rogues get hunted down like dogs by everyone on the server, my friend and I had to get a bit more creative in our efforts to introduce chaos.
We became very social. We would engage everyone we met in compliments and general chatter. Eventually someone bit. He thought we were nice, we liked his hat.
He was on the hook.
We invited him to our group, and played like normal. Extracted together once, then went to take out a boss and get some good loot.
Upon completion, and arriving at our 2nd extraction, my friend looked at me and gave the signal. I booted the player from our group, calmly informing him he had trusted the wrong guys. We gunned him down in cold blood and took the loot he was just bragging about.
He was audibly upset. We waited out our rogue status, then found shelter in a large group that was extracting elsewhere. The player we betrayed found us, he wanted revenge. He opened fire and we fought back. As we expected, every player nearby rained hell on this guy for going rogue and attacking us. He repeated this over and over, each time taunting us and telling us we're fucked. And each time he got killed by the crowd of players we hung out with.
You can try to become civil, Agents, but chaos will always find a way. Be careful in the Dark Zone my friends.
