There aren't a great many turn-based strategy games for the PSP platform, but Sony's new release, Field Commander promises to be a good one.

FC features different modes of play. Single Player Campaign, where one becomes a Field Commander for the Allied Nations, combating the Shadow Nation's campaign of terrorism and illegal arms shipments to rogue states. This mode features 30 different missions though a variety of realistic 3d environments.

One can also compete against one or more other players, either by sharing the device, or with someone nearby, using "ad-hoc" mode. Sony will also have a "matchmaking" service, where gamers can log on and find  potential opponents to play against. In Transmission Mode, one will be able to spend some time developing a strategy before sending their turn off to their competitor.

There will also be the option to play against other field commanders all over the world via "Infrastructure" or "Transmission" modes, customizing and sharing their missions with others. Although designed for the PSP, Sony will offer online support for the game. Official release is not scheduled until 22 May, but in the meantime, you can also play a sample of the game at the official website.

With 36 units, 11 officers, 15 units and a wide range of tactics, Field Commander should keep PSP gamers quite busy and happy for a long time to come.
