Solution: Shank 2 officially supports only 8–10 languages. You will need a fan translation patch. Search for “Shank 2 Portuguese language mod” on fan forums like Nexus Mods or Steam Community. These mods replace texture and font files.

The process on consoles can be a bit more straightforward:

"To change Shank 2’s language, open the main menu → Options → Language, then select the desired Text and Audio language. Some versions use your console’s system language — change that in the system settings if you don't see an in-game language option. Restart the game if prompted."

Change Shank 2’s language from the in-game Options menu — select Language/Audio/Text and choose your preferred language; a restart may be required.
