Rocket Raider

You are piloting a spaceship through deep space when you are attacked by a force of mutant alien craft. They retreat to a planet which you can see on your long range scanner. You decide to go down and investigate. You discover a plant scarred by four trenches, flying into them you find colonies of mutant invaders, fuel dumps, missile installations and drifting orbiting mines. Using your bombs and streams of laser torpedoes you must annihilate the enemy installations.
