Looking to add some more psychotic mercenaries to your life in increments of two, but light on cash in this ridiculously overstuffed Q1? Look to Amazon's Video Game Deal of the Day to fulfill your Army of Two: The 40th Day-related needs. For today only (or until the retailer runs out), both the PlayStation 3 and Xbox 360 versions of the co-op shooter are marked down to $39.99.
If that's still a bit much to pay (and if you're really desperate for some masked mayhem in a game), we'd like to suggest employing the same "buddy system" that Salem and Rios use. Buy it with a friend, play it together, and strengthen your relationship! You know, while blowing stuff up.
