The MP is not bad, it of course the wild west, the maps could be done a bit better to represent the topography of the terrain, but the waypoint system at least fixes that.
as far as the lone 'snipers' i found them annoying while in public free roam.. at least until I got my sniper rifle to take revenge, and yeah it is fun to just wage a battle when in a posse another posse, but there should be some common ground when someone is attacking a hideout to at least wait till the job is over before attacking each other.. c'mon we all get points when finished..
example, the other night my posse, of 4 guys were going to the fort and 2 noobs where up there firing cannons at us as we got close, I said screw this and went up on the ridge and sniped them and we took over the fort.. all we wanted to do was pass thru.. then it was on..lol
