Metro 2033 (original, non-Redux) is the first game in the Metro series, a first-person survival shooter set in the post-apocalyptic ruins of Moscow and its underground metro tunnels. You play Artyom, a young survivor navigating a world of mutant monsters, hostile factions, and scarce resources, using a mix of stealth, combat, and environmental storytelling in a dark, gritty, atmospheric adventure with intense encounters and scarce ammunition.
