Knights and Guns takes arcade-style shooters like Buster Brothers and adds a few things to make it unique. I can understand some people getting bored by the repetitiveness of the game and if you're looking for something that majorly shakes up the genre, you likely won't find it here. What you will find is a simple always-firing-upward shooter that lets you shoot monsters with several types of weapons, a campaign where you can take multiple paths to get to your final destination, and the ability to bring a friend along for the ride. For ten dollars, I'd say that's a pretty solid deal.
