Armchair generals, take note: tactical games are making a comeback. This top-down micromanaging genre was once dominated by the likes of Shining Force, Tactics Ogre, and Final Fantasy Tactics (and just recently by XCOM: Enemy Unknown) but it's surprisingly perfect for touchscreen devices; see the Great Little War Game series. The ARMA series is known for painstakingly realistic shooters, but it's stepping back for Arma Tactics THD to give the player a bird's eye view of the battlefield.
You control four commandos whose mission plays out on an impressive 3D grid, strategically moving and utilizing their weapons in turn-based combat. (If you're wondering what that's like, Call of Duty players, imagine chess with guns.) Each soldier specializes in a different tactical role, with unique weapons and abilities assigned to him.
