Yeouido is the fortified safe zone that the subtitle of NAKWON: LAST PARADISE refers to. It is the island district at the heart of Seoul that survives the citywide outbreak as the last surviving refuge, and it is the home base from which every nightly expedition into the ruined streets begins. For broader setting context, see the Seoul article; for the wider gameplay framing, see the overview.
What Yeouido Is
In the fiction of the game, Yeouido is the only quarantine zone that has held. The wider city outside has fallen to the infected, and the survivors who reached the walls now live as refugees inside them. The official framing places the player as one of those refugees rather than as a soldier or a free citizen. Daily life on Yeouido revolves around three pressures: paying rent on a personal shelter, climbing a Citizen Grade ladder that gates access to districts and equipment, and queuing up for the night expeditions that keep the community supplied.
Yeouido and the Day Phase
Yeouido is the place where the day half of the day-night cycle plays out. Activities inside the walls include placing furniture, upgrading workbenches, storing food, organizing loadouts, repairing or crafting gear, and preparing the next run. The zone has no expedition combat: it is the safe half of the loop, and it is the only place gear is guaranteed to survive between runs.
The Citizen Grade Economy
Yeouido's social structure runs on the Citizen Grade ladder, a money-driven ranking that decides what a refugee is allowed to do and where they are allowed to go. Higher grades unlock more privileges, broader equipment access, and likely more profitable expedition zones; lower grades restrict the survivor to safer routes and a leaner shelf of gear. The Citizen Grade article covers the mechanic in detail.
Real-World Reference
Yeouido is a real island district of Seoul, located in the Han River and home to several of the city's tallest skyscrapers, government buildings, and financial offices. The game uses the real geography as flavor for the in-fiction quarantine zone, but the dossier of confirmed facts does not commit to a one-to-one reproduction of any real Yeouido tenant or landmark. The wiki treats real-world Yeouido as inspiration, not as canon.
Yeouido and the City Outside
Yeouido is the inside; the expedition map is the outside. The closed alpha placed the expedition map in central Seoul, with most of the named landmarks anchored to the Jongno district. The transition between the two zones happens at the start of each night phase. Survivors queue up for an expedition, drop into the city, and have to make it back to a designated exit before they lose what they brought.
What Is Not Yet Public
Mintrocket and Nexon have not published a Yeouido district map, a list of named buildings inside the safe zone, or a roster of in-fiction NPC factions running the quarantine. The dossier of confirmed facts is limited to the social and economic mechanics described above. Anything beyond that, including the size of the population inside the walls, the legal structure of the refugee state, and the specific facilities available to the player at higher Citizen Grades, has not been confirmed and is left out of this article.
