Metro Last Light was released in 2013 by Ukrainian studio 4A Games as the sequel to Metro 2033, continuing Artyom's story in the tunnels beneath a nuclear devastated Moscow. Composer Alexey Omelchuk wrote the score, and the main theme became the game's most recognisable musical motif, closely associated with its guitar led menu and promotional material. As Metro edits, lore videos and atmosphere compilations grew online, the short theme was reused on its own, valued for how quickly it signals the series' bleak survival mood.
