Control your carrier and use it to take over islands so you get enough power to find and destroy the other carrier. The movie is not done by me (none of the movies i link to are) but it provides a good overview of the game.

3D combat simulator with tanks and planes. Collect five parts of a neutron bomb and use it the destroy the enemys beam cannon. You search the map while at the same time you destroy the enemys generators to delay the completion of the beam cannon.

A remake that fails. The basic idea is the same but they added horrible first-person segments and cutscenes. The AI units is a pain as you have to babysit them all the time.
