What to open first
Read the first night before you spend Robux or pick a class. Then use food and water if the taps are still running, and the door guide before you sprint the hall.
Later days
The objective guide and the roof guide are for runs that have already left Night 0. Day numbers come from filmed objectives. If Update 2.0 changed a line, the in-game list wins.
Which 30 Floors Up guides are published?
First night in flat 3004
Night 0 stores water on the living-room rack, moves every food portion into the pantry, then locks the door and lets Daniel in after the peephole.
Food, water and the day the taps stop
Fill every container before the taps stop, rack food so the pantry counter is real, and treat rainwater before you drink it.
Noise, doors and when to swing
Check the peephole, set the chain, then brace the door. Sprinting and melee are louder than walking, and a lock alone does not hold three infected.
Objectives from Night 0 to Day 38
Follow the top-right objective from Night 0 through the Day 38 kitchen run, and re-check the list if Update 2.0 has moved a day number.
Roof route and the way down
The Day 28 roof path is lift 2's shaft, a landing key and a wrench. Later objectives turn back down toward June on floor 19. No filmed ending is published.
Playing with up to three friends
A run is solo or four people. Split the bucket, the pantry and the door, and do not spend four searches on one Scavenger container.
