- 30 floors up 30 days of siege is a high-rise survival scenario where the city collapses while you're trapped on the 30th floor.
- Water runs out first: pumps need power, so fill the bathtub, pots, and bottles the moment the alert hits.
- Noise is a dinner bell: stay silent, shoes off, no shouting, no music.
- Smoke kills more than fire: seal door gaps with wet towels and never light a stove in a sealed room.
- The rooftop water tank is the endgame objective — thousands of gallons for the fire system.
The Scenario: What Happens in 30 Floors Up 30 Days of Siege
The premise is brutally simple. You live on the 30th floor of a residential tower, and until tonight that was just an inconvenience. At 9:40 PM, every phone in the building screams the same message: stay inside, lock your doors, do not help the injured. Down on the street, people are running — and some of them are not running away. What follows is a 30-day siege where every resource, every decision, and every sound becomes a matter of survival.

The scenario plays out as a countdown of resources. Power dies at noon on day one. The taps cough and stop. Food stretches to 11 days eaten normally, or 25 under rationing. Meanwhile, the hallway population outside your door grows from four figures to nine to twenty-three — none of them wandering, all of them facing your door. The tension comes not from action but from arithmetic: gallons, tins, and days.
Every warning in this scenario follows the same logic: do not help the injured, do not open the door, do not make noise. Compassion is used as bait, and sound is a dinner bell. The survivors who last 30 days are the ones who treat every human contact as a threat until proven otherwise.
Water and Food Management
Water is the first crisis and the one that defines everything else. A tower pumps its water upward with electricity, so when the power dies, the top floors go dry first. The scenario's protagonist fills the bathtub (about 40 gallons), then every pot, bottle, and sink — buying roughly six weeks at one gallon per person per day.
Water Sources Ranked
| Source | Yield | Risk Level | Notes |
|---|---|---|---|
| Bathtub fill (immediate) | ~40 gallons | Low | Must be done before power dies |
| Pots, bottles, sinks | ~10 gallons | Low | Done in the first hour |
| Rainwater on window ledge | ~3 gallons per rain | Low | Weather-dependent recovery |
| Rooftop fire tank | ~5,000 gallons | High | Requires shaft climb past threats |
| Neighbor's supply | Varies | Medium | Sharing doubles consumption rate |
Food follows a strict rationing order. The rule: eat the fridge first, then the freezer, cans last. A closed freezer stays cold for about two days once power cuts, so perishables are a countdown clock. Under rationing, half a tin per day delivers roughly 200 calories — a tenth of what a body needs. That is why the scenario pushes survivors toward the rooftop before weakness makes climbing impossible.
The toilet stops flushing by day three. Use a bucket, a bag, and a lid — and keep it far away from the bathtub. In long sieges, dirty water has killed more people than the fighting.
A sealed flat protects against smoke, but a flame in a sealed room produces carbon monoxide — odorless and lethal. Cold beans beat a warm death.
Security: Defending the 30th Floor
The siege logic is simple: doors break at the latch and the frame, not the middle. So that is where you brace. A bed plank wedged at 45 degrees between the door frame and the floor buys days, not weeks — enough time to execute the rooftop plan.
Home Defense Priority List
| Priority | Action | Effectiveness |
|---|---|---|
| 1 | Couch pushed against door | ★★ Delays entry briefly |
| 2 | Bookshelf stacked behind couch | ★★★ Adds mass, blocks latch |
| 3 | Bed plank wedged at 45° | ★★★★ Buys days, not weeks |
| 4 | Total silence protocol | ★★★★★ Prevents targeting entirely |
| 5 | Rooftop relocation via shaft | ★★★★★ Removes you from the flat |
The noise discipline is the real defense. Shoes off, no music, no shouting. The scenario's cleverest move is offensive noise: winding an alarm clock, setting it for two minutes, and dropping it down the rubbish chute. Thirty floors down it starts ringing, every head in the hallway turns, and twenty-three threats become four.
Silence Protocol
- Shoes off indoors
- No music, no talking near the door
- Listen more than you move
Door Fortification
- Brace at latch and frame
- Couch, then bookshelf, then plank
- Wedge at 45° for maximum hold
Misdirection
- Alarm down the rubbish chute
- Draws threats 30 floors down
- Clears the hallway for the climb
Fire, Smoke, and the Rooftop Escape
On the first night, three fires burn across the city with no fire engines coming — and one of them is in your building, on floor 11. Smoke climbs faster than anything, and you cannot go down. The answer is wet towels sealing every gap around the door. In a tower fire, smoke kills more people than flames, and the concrete structure eventually starves the fire of fuel. It costs four gallons you cannot spare.
The rooftop is both refuge and trap. The tower keeps thousands of gallons on the roof for the fire system — the gauge reads half full, about 5,000 gallons. But the stairs are full of threats, which leaves the service shaft: pipes, dust, and an iron rung every half meter.
Clear the Hallway
Drop a wound alarm clock down the rubbish chute. The noise pulls threats down 30 floors, reducing hallway numbers from 23 to 4.
Enter the Service Shaft
Use the same shaft behind the bathroom wall panel used for pipe-tapping. Every flat on that side shares it, and it runs all the way to the roof.
Climb Four Floors
Maintain three points of contact at all times — two hands and a foot, or two feet and a hand. Iron rungs appear every half meter.
Secure the Hatch
The roof hatch is unlocked. Sit on it with everything heavy you can find — this becomes your new front door.
Build the Camp
Sleep low against the tank: windbreakers on vent covers, tarpaulin on the sheltered side, cardboard underneath. The ground steals more heat than the air.
Up here you gain water, sightlines to the bank roof signaller, and separation from the hallway population. The trade-off is exposure — the first night outside nearly ends both survivors because wind strips heat faster than cold alone.
Allies, Signals, and the Radio Trap
Day 10 brings the first human contact: two knocks, then three, from inside the bathroom wall. The service shaft carries sound between flats. A spoon tapped back — three, pause, three — and for the first time in ten days, you are not alone.
Communication evolves as resources shrink:
| Method | Range | Use Case | Limitation |
|---|---|---|---|
| Pipe tapping | Adjacent flats | First contact, presence check | No complex messages |
| Bucket ferry (rope + coat hanger) | 3 m across the gap | Trading water, radio, batteries | Requires window alignment |
| Mirror flashes | Miles on clear days | Signalling the bank roof | Needs sunlight and line of sight |
| Roof paint messages | City-wide | Broadcasting warnings | Paint supply, exposure time |
| Radio broadcast | City-wide | Official evacuation info | May be a trap |
The scenario's darkest turn is the radio. It announces survivors gathering at the stadium — come on foot, bring nothing — repeating every hour in the same voice with the same pause in the same place. Then the bank roof signaller, who has been pointing at their own ear all along, finishes their final message before disappearing: do not trust the radio.
Two people means everything runs out twice as fast. The trade — a jug of water for a radio and batteries — buys information but doubles consumption. Choose allies knowing the cost.

- Fortify door at latch and frame with 45-degree brace
- Establish pipe-tapping contact with neighbors
- Execute rooftop tank climb before weakness sets in
- Verify any evacuation broadcast against independent signals
FAQ
Q: How long does water last in a 30th floor flat during a siege?
A full bathtub holds about 40 gallons, and one person needs roughly a gallon per day. Filling the bathtub plus every pot, bottle, and sink buys about six weeks. When power dies, the top floors go dry first because the tower relies on electric pumps.
Q: What is the biggest danger during 30 floors up 30 days of siege?
It is not the figures in the hallway — it is arithmetic. Smoke from a lower-floor fire kills more people than flames, dirty water kills more than fighting, and rationing at half a tin a day delivers only about 200 calories, making you too weak to climb within a week.
Q: Why is the rooftop water tank so important?
Towers store thousands of gallons on the roof for the fire system. In the scenario, the gauge reads half full — about 5,000 gallons — enough to outlast the siege. The only safe route up is the service shaft, cleared by dropping a ringing alarm clock down the rubbish chute first.
Q: Should you trust radio evacuation broadcasts during the siege?
Be skeptical. The scenario's radio repeats the stadium message every hour in the same voice with the same pause, and the bank roof signaller's final unfinished message reads 'do not trust.' Verify any broadcast against independent signals like mirror flashes before moving.
