Via WorthPlaying: "Although it is a bit difficult to enjoy the superficial story line in Army of Two, the game offers a merging of some of the most popular FPS features. If you prefer a solo run-and-gun experience, then this title definitely isn't for you. Army of Two requires cooperative gameplay even when using an AI teammate. The game sports an excellent weapons upgrade system, with an extensive number of weapons available for purchase and modification. The campaign is engaging and fun, especially when you play with a friend. Combined with an Xbox Live experience that offers some great replay value, all of these features make Army of Two a pretty good entertainment investment for mature players."
