"Front Mission 4" for PlayStation 2 is a turn-based combat-strategy game in which players pilot robots. All of these elements, except maybe the giant robots, are central to understanding the latest offering from Square Enix.

"Front Mission 4" follows two seemingly unconnected story lines. In the first, several German military bases are destroyed during surprise attacks. An investigation is launched by Durandal, a European Economic Community company similar to Airbus that makes giant combat robots instead of commuter jets.

The other story line begins like the movies "Four Kings" and "Kelly's Heroes," with a band of rules-breaking soldiers discovering a load of gold in Columbia. Instead of driving tanks, however, these soldiers drive . . . yup, giant combat robots.
