Hah, got to play some MP last night. Entered Free Roam mode, and spawn in the middle of nowhere with nothing but a donkey for transportation, and a few seconds after that some jackass in a horse comes charging at me blasting away. Took all 6 rounds from my Cattleman Revolver to put him down... and surprise, it was a Rockstar guy, bagged that achievement quick!
Roamed around for a bit, cleared out a gang hideout (hard to do when you only have a revolver), and then Shades4Hire invited me into his posse of 5. We were just leveling up and clearing out gang hideouts. Plays like a 6 player COD co-op, only Wild West style. So much fun!
Took a couple of crappy pics with my iPhone.
This guy (another XBL player) had the unfortunate happenstance of clearing out a gang hideout right before our posse got there (after traveling halfway across the world). With nothing left to kill, we ended up taking out our frustration on the poor bastard. We quickly surrounded him, and invited him to join our posse, or else. He never responded so we had to shank the bastard.
Then we found a stagecoach. Four us piled in while the others remained on horseback. With one guy driving that left 3 of us with nothing to do but shoot up the countryside. Hilarious, especially when your driver can't steer the horses for shit, almost pitching us off a cliff at one point.
Good times! Went from Level 1 to Level 7 in half an hour.
