Field Commander is a military turn-based tactics game for the PlayStation Portable. The player takes on the persona of a new Advanced Tactical Legion for Allied Security (ATLAS) recruit, an international military alliance. The player battles Shadow Nation, a criminal empire. Gameplay The multiplayer options include Infrastructure, Ad Hoc, Hot Swap, and a unique feature called Transmission mode, which is somewhat similar to the play by email system of older PC games. While playing in Transmission mode each player takes turns and sends them off to the server. Players can choose a commanding officer to act as the player's avatar. Divisions determine the player's allegiance as well as Division Bonuses that can be activated. Each division has a unique strength and a corresponding weakness. The Card Sharks, for instance, feature strong infantry units but they move slowly, while the Killing Depths' naval vessels deal heavy damage at the cost of having weak army units. Fuel and ammunition are finite for vehicles and primary weapons, while infantry have unlimited fuel and secondary weapons have unlimited ammunition. When fuel is exhausted, there is a high chance the unit will explode. All units can be resupplied by either trucks, transports, or cities. Fighting works similar to other games in the genre but had many unique elements which included the ability to destroy terrain, reduce and eventually destroy cities, special buildings that could call in attacks from off the board, such as Airstrikes, Napalm Launchers, Satellite Lasers, EMP and concussion blasts, stealth units in every terrain type, as well as the ability to stack units in a single tile. Stacking units could be taken to an extreme. A player can have a plane, a tank on a bridge, a boat under the bridge, and a submerged sub all in the same grid space. Certain terrain will slow down movement, or even be completely impassable. For example, the Teton cannot be traversed by any unit. Swamps slow down tanks and do not allow wheeled units to proceed. Some terrain also increase or decrease unit defense. Some units have a ranged attack, allowing them to fire on enemies from a distance, but firing will count as a turn unless that unit is under the effect of a division power. Revenue can be gained by capturing buildings, and some buildings provide more money than others. The game also includes a built-in map editor, which allows players to
