Tom Clancy's EndWar

You will either need a little luck against a normal computer, or a friend who will allow you to get the trophy faster. When playing with a friend, ask him to capture half of the “satellite channels” on the map. At the same time, he must gather six or more of his soldiers in one place. When it finishes with the last “satellite channel” you should go into Defcon mode. Use your weapon of mass destruction to destroy the crowd it has gathered and the trophy will open. If you play by asking the computer, then you should hope that it will gather six or more soldiers in one place by the time you have weapons of mass destruction.
