"Silent protagonist" usually refers to a player character in video game that does not speak throughout the whole game, except for short sounds or interjections. But quite a number of silent protagonists are not actually silent in-game. Other characters inside the game acknowledge them as a normal person who talks.
For example, in The Elder Scrolls V: Skyrim, the protagonist doesn't speak with voice -- but makes conversations with other NPCs throughout the story.
Today, we're counting down some of the most silent protagonists in all of gaming. These characters are not just lacking voiceover -- they're also silent throughout their respective games and don't make any sort of conversation.
