Planet Hunters — Seth McEvoy

More than an app! You make the decisions! YOU ARE THE HERO OF YOUR OWN SCIENCE FICTION ADVENTURE! Can you infiltrate the starship of the world's most dangerous villains? Or survive the dangers of an aquatic frontier? You work for the Interplanetary Spy Center, a far-reaching organization devoted to stopping crime and terrorism in the galaxy. While you are on your mission, you will take your orders from the Interplanetary Spy Center. Follow your instructions carefully. You will be traveling alone on your mission. If you are captured, the Interplanetary Spy Center will not be able to help you. Only your wits and your sharp spy skills will help you reach your goal. Be careful. Keep your eyes open at all times.
