Activision has removed the Favela multiplayer map from Modern Warfare 2 following complaints from Muslim gamers.

Until the content can be taken out, Activision has removed the map from rotation, and an Activision representative provided IGN with the following statement in response to upset fans:

We apologize to anyone who found this image offensive. Please be assured we were unaware of this issue and that there was no intent to offend. We are working as quickly as possible to remove this image and any other similar ones we may find from our various game libraries. We are urgently working to release a Title Update to remove the texture from Modern Warfare 3. We are also working to remove the texture from Modern Warfare 2 through a separate Title Update. Until the TU is ready, we have removed the Favela multiplayer map from online rotation. Activision and our development studios are respectful of diverse cultures and religious beliefs, and sensitive to concerns raised by its loyal game players. We thank our fans for bringing this to our attention.
