It is the far future, and earth has begun settling on planets in its solar system. However the three planets are now represented by their own nation, and regard the other ones with hostility. When new desirable planet is found, all three nations send forces to take it, and claim it as their own. Choose which planet you wish to represent: Earth, Mars, and Pluto. Use your mouse to select your troops, and use the keyboard hotkeys to send them out even faster. Each army has 5 upgradable attributes: Life, Damage, Speed, Reload, and Armor. Choose wisely which ones to upgrade and when, and overcome the two weaker planets.
