You command your starfighter through a very familiar trench-run over an alien complex or moon (no that's no moon, perhaps a space station?), shooting enemy ships and trying to blow this thing so you can go home. Wahooo!!
Mothership is composed of three scenarios. You have to complete each one before you can go on to the next one. First, destroy the dozen drones sent to attack you (in a row, without being shot), before your fuel runs out. In the second scenario, make your way to the top level of the ship. Use the joystick left and right controls. Push forward to jump. You have to ride the elevator to go to the next floor. Call it by pulling down on the joystick. The elevator can be ridden when it's green, but not when it changes to red. The mutant meanies or the flying scanners will dematerialise you if they touch you, but you can shoot them.

In the final scenario you must break through the barrier of energy pods to destroy the planet's generators. Each pod has to be hit four times (they change color on each hit). Red pods can be blown up with one hit. Beware of energy torpedo.
