Development studio 4A Games has released a new trailer for its upcoming shooter game Metro Exodus. The trailer sheds light on the weapon customization system in the game.

In the game players flee the shattered ruins of dead Moscow and embark on an "epic, continent-spanning" journey across post-apocalyptic Russia.

Players will explore the Russian wilderness in "vast, non-linear levels" and follow a storyline that is inspired by the novels of Dmitry Glukhovsky that spans an entire year through spring, summer and autumn to the depths of nuclear winter.

Metro Exodus releases on February 15, 2019, for PC, Xbox One and PlayStation 4.
