Played online for the first time over the weekend and I saw a guy using some sort of gun that wiped absolutely everything out. Everything! He killed the Rakk Hive after about 5 shots.
What on earth was that gun?
He was most likely using a modded gun. I generally play with a group of people I know, but if I ever go on xbox live with randoms, it seems like they always have modded weapons and shields.
