Mars Sucks is a Google Earth based game. If you do not yet have Google Earth installed you can get it by installing the Google Pack from the link on the right.
Once you’ve got Google Earth installed, follow this link to open a dynamic KML file from DestinSharks.com
To Play the Game:
1. Read the clues and search for the aliens (you’ll need to be below 2400 miles to see them and they don’t seem to appear prior to the 2nd clue)
2. Center your cross-hairs over the UFO and you will shoot automatically. To shoot again, move your view just a touch and stop. It takes 4 shots to destroy a UFO.
This is a great game to develop geography skills, and it’s amusing to blast the little aliens while you’re at it.
