Metro Exodus will be released exclusively on the Epic Games Store on Feb. 15, publisher Deep Silver and storefront owner Epic Games announced Monday. The game will launch for $49.99 in North America, and €59.99 in most European countries.

This means that Windows PC customers will not be able to buy Metro Exodus through Steam at launch, despite the game’s listing on Steam advertising pre-orders. “Any customer with an outstanding pre-order for Metro Exodus on PC through any digital retailer will receive their game as expected,” the announcement states.
