If you’re one one of the millions waiting anxiously for the release of Modern Warfare 3, look no further than this app from XDA member j.13.leach. Though the app is still in beta and the game has not yet been released, it functions as a comprehensive guide to many new perks, videos, maps, weapons and more. This isn’t the first CoD app to hit the market, but it may be among the few polished ones. It features updates twice daily, and even will alert you when new content is made public. Check it out if you’re into the CoD franchise, and tell us how it holds up.
