Sometimes a Video Game instruction manual, in the progress of describing gameplay controls or mechanics, will reveal information that was otherwise intended to be a surprise for the player as they play the game. For example, an illustration may depict characters that join the player's party late in the game, enemies or bosses they may fight in a particular area, or a page may discuss how to control the player's Global Airship. This is related to Trailers Always Spoil and Spoiler Opening. See Interface Spoiler where the spoiling is done by an interface element instead of a manual.
