The Martians have landed on Earth, and in Cowboy vs Martians it’s your job to save the world. Armed with a gun, you need to shoot all the Martians before they cause any trouble. The game starts easily before it gets progressively harder with each level. There are three stars up for grabs on each level, and the fewer shots you take, the more stars you’ll get – you’ll want to try again and again to get every one of them! The game is beautifully designed and you can now play it for free on Gamepix, where it’s presented in HTML5. Play Cowboy VS Martians now on GamePix!
