In a last-ditch attempt to recover their stolen equipment, the Computer Research Society challenges the SOS Brigade to a winner-takes-all game tournament! The game they've chosen: a multi-player space battle simulation game. Even though no one in the SOS Brigade has ever played the game before (some have never played any computer game ever), Haruhi readily agrees to the contest. Failure seems inevitable, but losing is not an option! Thankfully, the SOS Brigade members aren't just your average students. Can they pull it together to destroy the expert Computer Research Society before Haruhi destroys the whole city?
