The content in question concerns two paintings above a toilet in the level, containing the quote “Allah is beautiful and He loves beauty”.
Activision has claimed it was unaware of the paintings, saying they “apologise to anyone who found it offensive” and is rapidly engineering an update to remove them.
“We are working as quickly as possible to remove this image and any other similar ones we may find from our various game libraries,” the publisher added.
As Kotaku says, it can be offensive to those of Islamic faith to see holy teachings written on or in a bathroom. The paintings don’t appear anywhere else in the level.
