Call | Of Duty Mw3 English Language Pack

The primary challenge with the 2011 version is that some retail copies are locked to a single language. To convert a non-English version (like Russian) to English, some users resort to replacing the game's data files.

You cannot bypass a hardcoded physical region lock with an add-on pack. You will need to create a secondary console network account matching a region that supports English (e.g., a US or UK account), or purchase a digital version of the game from an English-supported storefront.
