Action Fighter (Atari ST, 3 1/2" Disk) Sega - 1989 USA, Canada Release

Description from the packaging.

Take to the streets. Or take to the skies.

Because Action Fighter is the incredible, transformable combat vehicle.

You start out on a customized cycle. Built with enough speed and power to jump over water and overtake enemies.

Then, by finding the right parts along the way, you'll change your cycle into a supercharged, state-of-the-art sports car.

Next, add two turbojets to make your car airborne. And take to the skies.

Down hyped-up helicopters and jet spaceships from above.

And no matter which vehicle you're manning- or who you're after- get ready to stand by for action!

Jump over water, blasting enemies to a watery death as you go.
This baby's fast.
But so are the guys you're chasing.
In the air, you've got a better shot at your adversaries. But then they have a better shot at you!
You'll always have a chance to get more ammo from the Sega truck.
Watch where you're going. Or the going will get rough.
