This game gives you a lot of options. You have to destroy a power grid before a missile is launched. You have a subterranean base where you can invent and construct vehicles such as tanks, hovercrafts, planes and heli's.
The 3D playfield is huge and you can roam around freely. Very immersive gameplay.
