Aoife Wilson reviewed Shadow of Mordor for Eurogamer, awarding it an 8: "Its open world doesn't always feel as big, busy or varied as you'd like it to," she wrote, "an understandable problem given that much of Mordor is a barren wasteland by definition - but you see Tolkien's uniting influence running through everything from the darkened slopes of Orodruin on the horizon to the skittering ungol underfoot."
