Uncharted 2 Co-op

When I played Uncharted Coop I can't believe some of these players--they are literally crazy. One guy he was bragging how good he was and I can tell you he was horrible and not a team player and kept on talking...another was down and was screaming for help and he kept going down because he kept rushing towards soldiers. At one point I gave up helping him because I got killed. This is the icing on the cake--they ask me if can add them on my list--I did not accept them as a friend. I just like to play the game and finish the stages. Also, I like to help players to achieve their goals for weapon upgrades.
