The game mode is very similar to the one in the original: a bunch of tanks fight for survival in a battle in turns where the last survivor wins.
You will earn money depending on the number of enemies defeated. That money will be used to buy more weapons. The list of available weapons is big enough.
Playing Atomic Tanks is easy. Choose the fire angle, power and the weapon. Take in mind the direction and the strength of the wind.
Finally, with this portable version you will be able to play it on any computer, just plug your USB Pendrive and enjoy yourself.
