Aliens

Aliens is a single player shareware game based on Taito's Space Invaders. As with the classic Space Invaders game the player has a canon which they can move to the right and left along the base of the game window. The canon fires upwards at the descending alien ships. This game varies from the original game in a number of ways:* Here there are no buildings to hide behind.

• In another variation from the original game the alien ships land and steal the planets resources, these ships must be destroyed once they take-off as if they reach the top of the screen the players score is reduced.

• Finally, the player must protect defending craft as they take-off. Shooting these down by mistake also reduces the player's score

The game is entirely keyboard controlled. The player's score is displayed in the game's title bar as the game progresses, there is no high score feature.
