If you want a really good game that will keep you busy for a while, then grab Chicken Invaders 5 Mac today. It's really a good game that doesn't take too long to play, so you should have plenty of time left over to spend doing other things.
I'm not going to go into detail about the mechanics of the game, except to say that you will move from one platform to another avoiding the nasty little bugs that fall from above and below you. Although the game is available for free, you can also purchase Chicken Invaders in the good-looking full version. The good thing about this game is that it's available for free on the Interaction Studios website. The control scheme is simple and the game plays great on both the Mac and PC, with modern touch screen mechanics making it very convenient. I loved the look and the sound of this new version as well, with nice bright colors and music. The game itself is very similar to the classic Space Invaders. The object of the game is to prevent the evil purple worms from taking over your domain by creating an impenetrable fence around it.
Chicken Invaders is a fun time management game from Interaction Studios.
