I think that in Civ4 you should be able to control a "Red Button" after the discovery of a modn tech ("Doomsday Devices"?). The button is placed where the normal unit control buttons are, and it is flashing red. It should be placed right next to the "Go" button. Or, it could be placed below the "Palace View - Victory Status - Espionage - SpaceShip" buttons to the right of the dataview.
When you press it, you lauch all of your items and then, depending on how many weapons you have, you get a neat 3D animation like the intro video that shows the world blowing up in pretty colors.
