Chicken Invaders (DX Edition) is the first game in the Chicken Invaders Series. The game features very simple gameplay, only one weapon, and the same waves every system. Unlike the others, this game never ends (you can read more on that here). It was released around July 6th 1999. The game's sequel is Chicken Invaders: The Next Wave.

Official Summary

Sometime in the near future, Earth is invaded by chickens from another galaxy, bent on revenge against the human race for oppressing earth chickens! Take the world's fate in your hands (or at least have an omelette) in this modern rendition of the 80's classic. Save the world today!


  • 1 or 2 players — play alone or with a friend!
  • Increasingly difficult waves — how far can you go?
  • Boss levels — watch out, these chickens are serious!
  • Weapon power-ups — advance your main weapon through 8 power levels! Collect Missiles, too!
  • High score tables — how high can you reach?


This game is and was always available for free on the official site. You can download it from here or from here.


    The UveDX version (the one we all know) wasn't actually the first Chicken Invaders ever. It just was the first one to be officially released, as before it came the disappointing Java version which was severely limited, and the BC++ version, of which some of its code is still in the engine to this day. Nothing much is left from those versions today, aside from this title screen of the DOS version.
  • This is the first game in the series that technically doesn't have an end.
  • You cannot move freely in this game, only left and right, mimicking the original Space Invaders which this game parodies.
  • The opening theme of the game is "Also Sprach Zarathustra - Op. 30" by Richard Strauss. This was likely chosen because it is the theme from 2001: A Space Oddysey.
