Pleiads
Pleiads is a space shooter from Thekan
Each round of play includes 4 different stages. Against a backdrop of planets and twinkling stars, the Earth City must be protected from sixteen attacking Martians. These Martian attackers have the ability to transform from flying Martians, to walking Martians, or to UFOs. The walking Martians build barriers across the Earth City. These barriers must be destroyed.
The Earth Spaceship can be maneuvered right and left. With the use of the 'warp' button, it can be randomly relocated when necessary. These, plus a backup of stationary defense weapons, aid in protecting the Earth City and Spaceship, as well as in destroying the Martian Attackers. When all but the two final Martians have been destroyed, a tone of dusk shades the Earth City. As these two attackers meet their end, the Earth Spaceship ascends into space to meet the challenge of Stage II.
