I can only stand shooting generic bad guys while spewing generic macho quips for so long before I get tired of it. Gears of War, Halo, even Modern Warfare all follow the same basic formula, just putting their own spin on it.
Army of Two: The 40th Day, however, barely adds any spin at all. At its deepest core, it is the formula."
