I'm Pissed
So, I'm just casually playing some Free Roam. There is a 3 man posse in the lobby, located in the place south of Pike's Basin. Thinking they were friendly, cool gamers, I ride past them on my horse. But guess what? One of them pulls a sniper and headshots me. Then, this little kid on the posse starts raising his high pitched voice saying he "owned" me. Shooting me with my back turned is not cool or skillful, so I send him a message about it. And being the little ungrateful sonofab*tch he is, he says that I'm just mad that I was killed. Seriously, Red Dead Redemption is not for kids who don't understand that Free Roam is not like CoD's multiplayer. It's not kill everyone that you see: its just casual gaming with friends.
Posse Battle
I jumped on the couch, ready for multiplayer. I got into a session with 2 of my friends. We created a posse, and we helped each other get challenges. Deciding to expand our posse, we started randomly inviting people we did not know. But apparently, the couldn't tell friend from foe. So they started shooting me and my friends. One of my friends yelled out "We made you!" while having his head filled with lead. So us and other posse members left the original and started a huge war in Chuparosa. It was complete CHAOS. The army was also involved as some players had bounties. Fire bottles, dynamite, snipers, throwing knives, the list goes on.
