Pleiades

Pleiads is a multi-stage space shoot 'em up in which enemy ships fly at the player in waves in a similar fashion to games like Galaxian and Phoenix. Ships emerge from a mothership at the top of the screen and swoop downwards in a series of patterns which players must anticipate as they shoot the ships and avoid being obliterated by the Martian onslaught. There are four stages in the game. In the first stage the Earth space ship must defend the space station from Martian invaders who have the ability to transform from flying invaders, to walking invaders who build walls across the Earth city; these barriers must be destroyed. At the end of stage one the Earth space ship flies to the top of the screen to prepare to meet stage two. In the second stage the player encounters eight space monsters who must be hit directly on center to be destroyed before moving onto stage three. In this stage invaders emerge form a space ship at the top of the screen and swoop down on the player in sweeping attacks. In the final wave the player has to navigate through parked spaceships to dock on a landing pad as the screen scrolls downwards. Extra points can be gained in this stage by collecting flags as the player moves towards the landing corridor.

The rules of the simulation have been altered in a potentially deadly manner, with the player's consciousness trapped inside. There is only one possible way to escape, by completing the game with a period of 48 virtual hours. The penalty for failing to do so is the ultimate one – real death.

Alien Invaders is a variant of Space Invaders . A 14x5 rectangular formation of enemy spacecraft appears from the top of the screen, and slowly gets closer to the surface of the Earth. You control a mobile missile launcher that can shoot up at the invaders, while the aliens try to bomb you. As in Space Invaders, there are fortifications which can give you some shelter from the bombs, and these are slowly worn away as they are bombarded. There is also an enemy mother-ship that appears overhead, which gives you bonus points. But unlike Space Invaders, there is only one wave. Once the main enemy formation is defeated, you can only gain more points by aiming at the mother-ships until the five minute timer runs out.

Astro Invader is a fixed screen shoot 'em up. The player moves their laser base across the bottom of the screen and has to shoot down the aliens that appear above. What sets Astro Invader apart from other early shoot 'em ups is that the aliens, after being dropped from their mothership, position themselves in columns. Once a column is full the lowest alien drops down and suicide dives towards the player. As they hit the ground they explode and the player must make sure they are not within the blast radius. In addition to the standard aliens there are also UFOs that appear in the middle and to the sides of the screen. These must be shot down as they will kill the player when landing, no matter where the player is positioned. The game is over when all three lives are lost.

In this timed game, you have two minutes to build a space station from four pieces that are floating around in space.
