I used to play horde mode in local co-op with my friends for hours and then get on xbox live and play hyper competitive matches with my "Clan" (group of fifteen year olds like me.) I think this was some of the most fun I had in multiplayer when I was younger, but it doesn't super hold up in modern age. The story is actually really good for such a testosterone pumped game, with characters genuinely coming off as vulnerable, often. Worth a play.
