In our massive review of Dishonored, we likened the game very strongly to Half-Life 2, and not least of all because you’re a completely mute protagonist who takes orders from everyone. It turns out that this wasn’t always the plan: speaking to Official Playstation Magazine, creators Raphael Colantonio and Harvey Smith revealed that Corvo was originally intended to have a voice.
“(Making him mute) was a deliberate choice,” said Raphael (or possibly Harvey). “If we portrayed Corvo angry and seeking revenge, it might offend the nonlethal player who is seeking a stable outcome for the City of Dunwall, and vice versa”.
“We added some text input options for Corvo around alpha but never really went further. To this day, we wonder what the other version would have felt like in the game”.
The interview also revealed that the original pitch for Dishonored, in its shortest possible form, was “ninjas”.
