Alien (Atari 2600)
'Alien' is a 1982 maze video game for the Atari 2600 published by 20th Century Fox.
Based on the 1979 eponymous science-fiction film, Alien is a game title written by Doug Neubauer, but credited in the packaging as "Dallas North". Alien for the Atari 2600 is the first officially licensed game of the Alien film series.
The player controls a member of the human crew pursued by three aliens in the hallways of a ship. The goal is to destroy the alien eggs laid in the hallways (like the dots in Pac-Man). Additionally, "pulsars" (similar to the power pills in Pac-Man) occasionally appear which turn the tables, allowing the human to overpower the aliens.
Despite having many features heavily stylised after Pac-Man, it has the inclusion of a bonus round after each successfully completed stage. It places the human (player) at the bottom of the screen, who must persevere through several rows of aliens in order to reach the prize at the top. Claiming the prize awarded the player with bonus points for that session.
