The Metro Exodus expansion pass will include two brand-new story campaigns set after the events of the main game. Those who haven’t finished the game yet and don’t wish the narrative to be spoiled should skip below to the release date and pre-order information.

Each new story campaign stars a character other than Artoym. The Two Colonels is the first and is told through the eyes of Colonel Khlebnikov — a new character — while the second, Sam’s Story, centers on Sam (surprise!), the only American in the Aurora Spartan Rangers.

The Two Colonels is set to launch this summer and follows Khlebnikov’s journey under the dead city of Novosibirsk as he tries to make his way home to his son Kirill in time for New Year’s Eve.

However, Novosibirsk is in trouble. The material people use to defend against radiation is running out, and mutant monster attacks are increasing. Khlebnikov’s journey through the city during its last days lays the foundation for Colonel Miller’s tale a year later.

Sam’s Story is slated for an early 2020 release date. Where The Two Colonels is a linear story, Sam’s Story will be a sandbox-style survival adventure. Sam is a U.S. Marine at the diplomatic embassy in Moscow before the world is nearly obliterated by nuclear bombs. He only wants to go home to his family, but initially believes, like everyone else, that Moscow is the last city left on the planet.

When he finds out otherwise, Sam tries to make his way back home. The DLC campaign will focus on his danger-filled time in Vladivostok, navigating industrial ruins and decrepit residential districts as he tries to make it out alive.

The expansion pass will be available for PC via the Epic Games Store, PlayStation 4, and Xbox One.

Metro Exodus is already having a big year. Not only did it cause a ruckus when Deep Silver and 4A made it exclusive to the EGS on PC, but it also managed to outsell its predecessor and has already received a major update to improve the game’s quality and content.
