The Alien film franchise has inspired a great many games on various systems, from retro to modern.  Some games based on the movies, others extensions of them, while others mix it with the Predators franchise.  So, let's go down memory lane and look at those games where Aliens have been an inspiration.

Let's get started with the very first game that came out and the hack of that game on, none other, than the Atari 2600 in 1982.  Yep, it may not look a lot like anything related to the movie, but this was the first licensed game based on the franchise...

This hack has changed the alien sprites to resemble those of the movies, tying it better to the franchise.  Sadly, the video lacks sound but you can see the visual changes.[/align:j60yzo8g]
