Ahead of the anticipated release of Metro 2039, the complete Metro series to date is available at a substantial discount, with all three titles purchasable for less than $9. This promotion includes the remastered editions of Metro 2033 and Metro Last Light, collectively known as the Metro Redux Bundle, which can be acquired for $2.99. Additionally, the Metro Exodus Gold Edition, featuring all post-launch downloadable content, is available for $5.99.

The Metro series immerses players in a post-apocalyptic Russia, two decades after a cataclysmic event has rendered the surface uninhabitable due to radiation and mutated creatures. Players assume the role of Artyom, a survivor venturing from his underground sanctuary. The initial game, Metro 2033, centers on a quest to warn other metro stations of an encroaching mutant threat known as the Dark Ones. Its successor, Metro Last Light, continues the narrative with gameplay enhancements. The most recent entry, Metro Exodus, sees Artyom journeying beyond Moscow aboard the Aurora train in search of life elsewhere.

Across all three titles, gameplay is presented from a first-person perspective, confronting players with both human and mutated adversaries. While resembling typical first-person shooters, the Metro games emphasize survival mechanics. Limited resources, including ammunition and vital gas mask filters, necessitate strategic decision-making, where every bullet and every use of protective gear is critical for survival.
