Mars Invasion

Mars Invasion is a great, fun mobile game that can be downloaded to your cell phone or PDA. In fact, it is one of the best free games I have played. That's because it's incredibly addictive. Unlike most free games, the levels just keep coming and coming, each one getting harder and harder.

The concept is simple. You are invading Mars. You have to capture a certain percent of the territory to move up to the next level. On the first level, you need to conquer eighty percent of the area. By the ninth level, that percentage has been increased to the almost impossible eighty-six percent.

While you are going around conquering area, the Martians are fighting back. Every level, there is one more Martian you are faced with fighting. So on level nine, you are facing nine separate enemies, all intent in reclaiming the land you have conquered already. That is what makes the game so challenging. At one time, you are just two percent away from finishing the level. Then the Martians come along and all of a sudden you are ten percent back.

You start off with three lives. After level four, you earn an additional life for every level you conquer. If you spot a special power-up, drive over it and you can gain a turbo boast or even slow the Martians down with a freeze ray. But be careful, these effects are only temporary. At any time, the Martians come back to life with a vengeance.

A great strategy is to create traps for the Martians and divide and conquer. Keep them apart and you will have an easier time conquering territory. Otherwise, there will be just too many of them in a small space for you to do any serious damage. Conquer small bits of territory at a time, it is a much safer than going for a quick win (although quick wins are more satisfying.)
