Return of the Invaders

I didn't play this much as a kid, but I sure remember it. Return of the Invaders is to Space Invaders as Galaga is to Galaxian - more complex, more colourful, more fun. Weapon powerups (rapid fire!) can be collected my shooting the mothership. Leaving a row of top level invaders takes you to a 'challenging stage'.
