Raiden II
Excellent sequel to the classic original "Raiden". As in the original, players control a fighter jet/spaceship through various levels while shooting down other planes and bombing tanks on the ground.
Story
Three years after the World Alliance military triumphed over the Cranassian invasion force, the aliens remaining on Earth have raised an army to carry out their original mission to conquer the planet. To combat the collaborative army, a new weapon is being developed for the Raiden - the ship that was supposed to save Earth three years ago - to use in another attempt to save our planet.
