This is a short story based in the world that the video game Arc Raiders takes place in. If you are unfamiliar I have attached the lore below.
ARC Raiders lore centers on humanity's struggle for survival underground after a cataclysm known as the Collapse (around 2180) devastated Earth, followed by the arrival of mysterious, advanced robots called ARC, forcing survivors into subterranean cities like Speranza (in former Italy). Raiders risk the dangerous surface to scavenge resources, battling waves of increasingly advanced ARC machines, while uncovering clues about the machines' origins—speculated to be linked to humans who escaped Earth via an "Exodus" project or an AI takeover, with the machines possibly trying to reclaim the planet.
