The dates have changed, but the situation is the same. The Lone Star
System has once again waged war against the peaceful Planet Nebula. Her
wounds only recently healed, it's taken eighteen years for the planet to
reverse the decimation and destruction the last attack left behind. Led
once again by Reficul, Emperor of Lone, he's launched a fleet of attack
ships to thwart any attempts to stop him. And that includes you.
The mother ship Plealos is docked at Nebula's spaceport. She and her
crew are commanded by Reficul inside the ship. It's your mission to
pilot the super space jet Thunder Force II and guide it strategically to
the port deep below the planet's surface. To succeed, you need to
survive. And it won't be easy with five levels of intricate places to
pass through where ultra combat weapon forces wait to demolish your ship.
But first you've got to get there. Flying high above Nebula, the scene
below looks very bad. And if staying out of the line of fire seems
difficult now, be prepared for the worst later. Because once you're
underground, even obstacles pose a threat to your chances for survival.
This is stuff that separates the men from the boys. So good luck brave
one, and remember, heads up!
