One of the highlights of The Game Awards 2017 was a meaty trailer for Metro: Exodus, the latest installment in the post-apocalyptic survival horror shooter set in Russia. It showed familiar aspects Metro fans will recognize like mutated creatures and very hostile and inhospitable outdoor environment.

The trailer opened with voice over, "There's no one out there Artyom, no one to help us, no one to hear us," said a female voice. Returning protagonist Artyom is shown walking through a frozen wasteland. The buildings around him are destroyed and the world seems lifeless. And yet, Artyom keeps going out into the wasteland, looking for something.
