The story of Spaceteam is that you and the other players, who all have to be in the same vicinity of each other, are controlling a disintegrating spaceship. Each person has a part of the control panel that only they can control. Instruction are shown on your screen by the ships computer and you have to execute them to save the ship. The only problem is some of the instructions aren't on your control panel -- you have to should them at each other to get them done. Amazingly fun. Might even make a good drinking game.
Take a look at the video below to see what the game looks like while playing.
