Forgive me for saying so, but if you all you have to say in a reply is to tell me how little time it took you then you're kind of a jerk. Thanks to the people who offered tips, but the other 95% need to grow up. If you have no useful suggestions, why bother responding? To feed your ego? I'm kind of amazed by the number of people who think all the strategies needed to complete something like this is a short time are obvious, or that when you're playing with other people they're going to work with you and play smart. Several people said to shoot it in the legs. I do, because I shot it in lots of places and noticed where I get the most damage, but others may not, so I might be the only one shooting a given let. I've played it with two randoms and with a friend and one random. It was never fast. The time I did it with the two randoms it took so long one of them quit. Some people die a lot, and if they're not in a place where they can be revived they're not helping until they respawn. Some people seem to spend a good bit of time waiting to respawn, which is soooo not helpful.
