Ken McKown writes: The hack and slash field is slowly gaining momentum. With Torchlight II and Diablo III on the horizon and the original Torchlight and Dungeon Siege III occupying a lot of gamer’s time, the genre is definitely going strong. Microsoft hopes to capitalize on this with their latest Xbox Live Arcade effort from developer Certain Affinity called Crimson Alliance. This top-down slasher borrows from some of the veterans but offers up very little when it comes to customization and character progression. While it may turn off some, the game is still a blast to play, especially when you find three friends to go at it with.
