Two choices, and neither is a boss fight
The Roblox description asks whether you will wait for rescue or risk everything for a way out. It also names rooftop shelters, new routes and secrets. It does not name a floor-30 boss, a minigun or a climb that starts at the lobby. You already live on floor 30.
The lobby boards read Total Days Survived and Successful Evacuations. That is evidence an evacuation can be counted. It is not a filmed ending. No public run in the notes used here has shown the final scene.
Day 28 roof route
This is the objective text from the run that reached it, not a shortcut you should take on Night 0.
- Get the lift landing key. The objective says to look in the toolbox at home.
- On floor 30, open lift 2's landing door. The route is the shaft, not the stairs.
- Climb the shaft ladder. Unclip the gate and shove the loose panel aside.
- At the top, undo the machine-room hatch with a wrench.
- Go out through the machine-room door onto the roof.
The same notes say to talk to Arthur before you trust the lift. His dialogue includes the roof key. A follow-up from the player who filmed the wrench search says to talk to Arthur, use the triangular key on the lift, then use the adjustable wrench. Wrench spawn points named in that same comment, as places to search rather than a single guaranteed drawer: the room next to the lift, Eli's room, or the office below floor 28. The toolbox on floor 30 by the locked gates is another reported wrench spot, opened with the emergency cupboard key from the neighbor you can help at the start. Those are search locations from players, not a loot table.
If the maintenance key from Arthur does not open the trapdoor, the filmed alternative is the second way below floor 28: go up, or open the lift door, instead of forcing the one hatch.
What the roof is for
The mapped roof has a tank, a hut and the machine room. A roof tank is finite. Roof barrels catch more rain than a balcony bucket. Raw pigeon has to be cooked before you eat it, at the marked open-air station. Rain on Day 6 is listed from 09:00 to 17:30.
A rooftop shelter in the building projects is a lean-to against the plant-room wall:
- 4 bundles of planks
- 1 box of screws
- 2 folded blankets
- 1 coil of rope
Order written down: left post, right post, ridge beam, rafters, brackets and screws, blanket cover left, blanket cover right, tie-downs.
A pigeon trap on a ledge takes 1 bundle of planks, 1 wire mesh roll and 1 coil of rope: base boards, mesh enclosure, drop door and trip cord, then bait. The west and east ledges use the same list. Pigeons leave if you disturb the roof with noise or bright light. A trap still holds one bird. The Trapper class builds and resets traps faster, uses half the bait, and scares the flock less. It does not make the flock unlimited.
Seed packets are a roof item in the map notes. Seedlings need about 1 L every two days.
Going down after the roof
The same long run switches downward on Days 31 to 38. Floor 27's management office, the north-tank riser, the chained fire doors under 27, Arthur's leftover on the floor 26 landing, then June on 19 and the clinic on 11. Stair A is the upper stair, from floor 26 to floor 31, and it is described as packed when you go for Arthur. Below 26 it is blocked in the later objectives. Stair B is the long way down: floor 30, 19, 16, 11, ground, garage. The service door in the floor 27 office is how the notes reach the shaft and Stair B.
June wants two empty water containers. The Stair B barrier below 19 has to be fixed before Day 40 with a hammer and a board.
Nora's way between floor 10 and the ground floor takes about 40 minutes each way. Hunger and thirst keep counting. You cannot take it while something is chasing you. A handcart hauls whatever is on the cart pad at one end to the other end with you.
The bathroom vent on floor 30 is a second way out of the flat. Crouch. Buckets, boards and furniture do not fit.
Garage, if you get that far
B1 is parking. The basement cistern is the last big water reserve and it never refills. A generator there charges batteries and calls the infected. Every run burns fuel that does not come back. Generator noise is the highest value on the noise list, 110.
What not to promise your team
Waiting for rescue is a real option named by the developer. Finding a way out is the other. Building the shelter, cooking on the roof and opening the shaft are preparations and objectives that have been seen. They are not, by themselves, the evacuation that the lobby board is counting.
