Because of your reputation as a clever and daring memeber of the
MEGAFORCE, you have been sent to Sardoun, a strategically important
Democratic nation currently under attack. Your mission is to destroy
the Enemy Headquaters. Armed with the world's most advanced fighting
machine, the Moto-Fighter, you are dropped off just outside Sardoun.
You must pass the city and make your way across the barren desert to
the Enemy Headquarters on a limited supply of fuel. You'll be
challenged the entire way by heavy air and ground attack. Should you
travel too far into the barren desert, flashing arrows will direct you
back toward the enemy--that's the only help you can expect.
