The game - Pleiades - Atari 2600 | A2600

Hostile aliens are looking for trouble... and they've found you! Race your spaceship, it's time to defend against wave after wave of alien invaders, attack the mother ship, and weave through the tight parked spaceship runway! If you survive to the end, get ready, because this is not the end. They will be back - and faster than ever! Are you ready to take on the Pleiades and save the galaxy?

Pleiades is a port of the Centuri arcade game of the same name. It was programmed by UA Co., Ltd. the same companies that programmed all the games for Emerson Arcadia 2001. Pleiades has three unique waves of action and seems to be almost complete in terms of programming. It is unknown why this game (and other UA prototypes) was never mass-produced.
