I finished GUN: Showdown, and I've gotta say, it's the most exeedingly average game I've ever played. GUN has average shooting gameplay, slighty-shorter-than average run time (I beat the main story in about 5 hours), nice graphics with some glitches, but besides when performing missions, the game is very empty, and good a good story that is too rushed to be considered more than average. Review forthcoming, I think.
