Blueprint

CBS Electronics had a contest with this game. You had to uncover the hidden password TEALPEHN (after 8 levels of play) and then send in an entry form to enter. The word was 'your key to exciting new surprises from CBS Electronics'. Other than the fact the word can be anagrammed into either ELEPHANT or THE PLANE (a reference to the upcoming Wings perhaps?) nothing else is known about it. After uncovering the secret word, a box with an X inside it appears on the title screen.
