Do you like destroying everything that dare enters your path? However, are you tired of random sandbox games where you must complete story modes and missions and little tasks just to enjoy something.

Most of your worries have been solved.

Now, with this, you can eliminate humanity without the limitation of pesky goals! Destruction is at your hand now; its just requires a press of a button in order to hear a scream as a person is crushed by a boulder or disentigrated by a massive laser! None of the humans can build anything to stop you, they just hope that they can build fast enough to counter your chaos and mayhem! Make room for a new domininant race!

To start off, you are at a little menu. Just click play, and you are already at the action. No cutscene or story to worry you. You will have a little toolbar in the top area of the screen that shows you some number keys. They correspond to your keyboard, and you can use the highlighted ones. As you raze buildings and deconstruct people, you get more destructive toys to play with. By this time, the puny mortals are trying to build houses and hospitails, to house the homeless and treat thier wounded. Show them who's boss!!! >
