The only thing preventing people from really getting high sudden death records in multiplayer is that in life it can be a little difficult to count on 4 straight uninterrupted hours to play a game with someone. If one could pause the game for bathroom breaks, food, and such on blitz servers that would be amazing, even if it required all the people in that game to be in the escape screen or something.
This too, but I used to have a record of 829 and would really like to get it again only this time with friends.
