Pikmin is an odd game that requires a huge emphases on the "zerg rush" to defeat enemies. The hero unit/protaganist, is Captain Olimar an alian space shipment worker on vacation who crashed into an astroid (or meteor), and is stranded on a strange planet. He now haves 30-days to get 30-ship parts before his life support system is depleated. Luckily he finds the natives to be friendly or, at least the Pikmin. Olimar now haves the means to get back home (he misses his wife and children), and away frome the poisonous (oxygen filled) air of this hostile planet.
