Several pages at the end of the book describe some basic programming commands (“if,” “then” and “else”) and how they function together in a game.Getting sucked into a video game is not as much fun as you’d think. An action figure of the drill sergeant sitting on his nightstand tells him he needs to go back in and save Mark. Jesse wakes from a bad dream about his time in the game. Two weeks pass, and no one sees or hears from Mr. Gregory tries to deny the possibility of what they’re saying, but he looks nervous and pale. They tell him Mark is still trapped inside. Gregory and explain what’s happened with the game he created. The boys are zapped back into Eric’s house, but Mark isn’t with them. They shoot the drill sergeant, causing him to fall on and destroy the Hindenburg. With Mark’s help, Eric and Jesse battle more aliens and evade the Hindenburg to find themselves back at the beginning of the game. Errors, like Jesse and Eric, are to be sent to the Black Box from which there is no escape. Now, because Jesse and Eric created a problem, the Hindenburg character is after *them*. A character in the game is designed to fix any glitches that occur. Mark explains the Hindenburg protocol is an action built into the game to repair errors. Mark looks like a grown man and says he has been trapped in the game for 20 years. They learn the man is their former classmate, Mark, who went missing a month earlier.

As they try to fight their way past the aliens, a man rescues them and drives them through a crocodile-infested swamp on a hover tank. The boys realize the game is glitching and they’re trapped inside. Their action causes an error that initiates a Hindenburg protocol. The game wasn’t built with this scenario in mind. Jesse is beginning to enjoy himself when the boys blast an enemy creature at the same time. The boys use jet packs to travel through different levels, each of which mirrors a famous city. Eric also says there are easy escape routes when they want to return to the real world. He finds Eric, who assures him they can’t really die in the game. With the help of a computerized drill sergeant in the game’s tutorial, he learns how to blast the aliens shaped like bats, praying mantises and sand monsters. He hits a few buttons on Eric’s video game controller and finds himself inside the game. Jesse walks over but can’t find his friend anywhere. One day, Eric calls Jesse insisting there’s something he has to see. Eric is currently testing an unreleased game called Full Blast created by their friend Charlie’s father, Mr. His best friend, Eric Conrad, loves them.
