It doesn't sound like anything special, but the five key words which Gamelion uses to describe Allies in War are "fun, simple to use, addictive, social, and combat". This, paired with the quality cartoon-style visuals that almost made us reinstall Red Alert II, makes the game look rather promising.
Also, it appears that Gamelion has already delivered an update to Allies in War, version 1.0.2. It adds Game Center friends support, performance and gameplay improvements, additional sounds, and more. The game requires iOS 5.0 or later and is optimized for the iPhone 5, although any strategy game more elaborate than Plants vs. Zombies simply calls for a tablet.
