"The Chimeran gun tower is a form of Chimeran technology that is used to protect the European coastline from invaders. Over the course of the two years that the Chimera had occupied Europe, they built several of these gun towers all over the northern coast of the continent, making any kind of aerial invasion impossible. They only appear in Resistance: Retribution in the first mission in Rotterdam."@en . . . "Chimeran Gun Tower"@en . .
