In 1982, in an attempt to cash-in on the success of the sci-fi horror movie Alien (1979), Atari produced a tie-in video game for its Atari 2600 games console. The game itself bore little or no relation to the movie it was supposedly based on. Taking the existing Pac-Man style game format and re-engineering the sprites to look something like elements of the movie. If it wasn't for the game box cover and the instructions, you'd never have guessed that this game was Alien.
The maze, looks like the Pac-Man maze in shades of blues, but was meant to represent the inside of the Nostromo. Aliens are running rampant around the corridors of the spaceship (replacing the Pac-Man ghosts), the player clearing the alien eggs that line the corridors of the maze by running over them Pac-Man style. Yeah, it's just a bad version of Pac-Man with all the fun and cuteness of the original game sucked out of it.
