Johnny Maxwell is shocked to find that the aliens in his computer game are talking back to him. They are conceding defeat. What can he do? What must he do?

Though this book has apparently been updated (in 2004) from the original story (published in 1992), it probably needs to be updated again. Lots of computer talk and popular lingo that has changed dramatically in the past few years and would leave a modern child feeling a bit clueless.
