Your objective is to kill off as much of the enemy's civilian population as you can using a combination of missile silos, bombers and submarines all of which carry nuclear warheads with delivery systems of varying power. You have to think carefully before you create your bases and silos based on your territory and decide on fleet strengths and their locations. As the game progresses you get to see every little step you took get magnified. Every decision matters and there are many different ways of playing. The graphics are simple and distinctive and the music provides a great background. I've been playing for about 4 days now and its a little tricky when you start but once you get the hang of it you really appreciate the different strategies you can use. Multiplayer is fun with alliances forming and crumbling, a bit of backstabbing goes on but that's just another thing you have to factor in while deciding what to do when playing. If you like strategy games and don't mind putting in a few hours to learn then don't hesitate. Buy this game.
