Bullet Storm was the most fun I've had with shooter in a long time. I also love that the game didn't care if I was following the story, as long as I was having fun. That said it was straight forward and fast paced. Sadly I picked this game up super late and only payed $20 for it. I would have payed full price and I don't think I'm alone. We all overlooked this game yet we all NEED to give it a try.
Pros - Awesome gun play, you can Duke boot people, the characters are freaking awesome and voiced awesomely.
Cons - Online is just bolt-on and only kinda fun... for about a min or two, story is crazy as hell and they meant it to be... but it was only 2/3 good and 1/3 just crazy in a "alright" way.
