The Roblox listing asks you to last 100 days in an apartment 30 floors above a zombie outbreak. You store food and water, barricade the flat, and move quietly. Solo play and a team of up to four (you plus three friends) are both in the description. A server holds 30 players.
You start on floor 30 of Bellwether Heights, in flat 3004. The door numbers around the corridor include 3001 Ruth, 3002 L. Brandt, 3003 Daniel and 3005 Mara. Later objectives send you down the building. You do not start at street level and climb to a rooftop boss.
No code string is confirmed, and checked lobby shop tabs (Classes, Shop, Gems, Donate) did not show a code box. Codes published for other Roblox games, including 18 Floors, are for those games.
The live experience title reads [UPDATE 2.0] and the Roblox page shows an update stamp of 11/7/2026. That stamp does not include a public list of new floors, weapons or balance changes. Treat detailed routes from early-November footage as the last observed objectives, and re-read the in-game objective list if a step no longer matches.
